Let’s take a look at the latest research on this compound (cas:814-94-8).

A tin dioxide/carbon composite (SnO2@C) with controlled shape is fabricated using a two-step method, which includes preparation of SnC2O4 precursors and subsequent heat treatment process. SnC2O4 precursors with different morphologies are synthesized by controlling the different proportions of tin sources, and some characterization techniques are carried out to screen out the optimum precursors. And the precursors are further annealed to obtain nanostructured SnO2 and coated with carbon film. Ultimately, shape-controlled SnO2@C anode materials are prepared, and the reaction process and electrochem. properties of SnO2@C composites as anode materials are further studied. The SnO2@C composite shows the capacity of 659.4 mAh g-1 after 100 cycles at a c.d. of 100 mA g-1. Even at the rate of 2000 mA g-1, the composite electrode can maintain a reversible capacity of 507.2 mAh g-1. The excellent electrochem. performance is beneficial to the synergistic effect between the carbon coating film and the nanostructured SnO2, which provides sufficient lithium storage sites, good electronic conductivity and void space to relieve the volume expansion.

Author is Fedorenko, George; Oleksenko, Ludmila; Maksymovych, Nelly; Vasylenko, Inna.

Abstract: Highly sensitive to H2 sensors were created on the base of material obtained through tin (II) oxalate oxidation by hydrogen peroxide water solution It has been established that the addition of 0.1 wt% Ce to the sensor materials significantly increases response values of the sensors to hydrogen micro-concentrations in air (44 ppm H2). Nanoscale nature of the obtained sensor materials was confirmed by transmission electron microscopy and X-ray diffraction anal. The average particle size of the obtained 0.1 wt% Ce/SnO2 sensor materials was found to be 10.6 nm. The sensors doped with 0.1 wt% Ce exhibit enhanced gas sensing properties: a wide concentration range of H2 detection in air, relatively high selectivity to hydrogen and good repeatability of the response to H2 during long-term sensor operation (2 mo). Anal. of the previously reported data has revealed a promising combination of high sensitivity to hydrogen and fast response time with low Ce loading for sensors based on Ce/SnO2 material obtained in this work.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 814-94-8, is researched, SMILESS is O=C([O-])C([O-])=O.[Sn+2], Molecular C2O4SnJournal, ACS Applied Energy Materials called Scalable In Situ Synthesis of 2D-2D-Type Graphene-Wrapped SnS2 Nanohybrids for Enhanced Supercapacitor and Electrocatalytic Applications, Author is Lonkar, Sunil.

Recently, the development of layered two-dimensional (2D) material-based nanostructured hybrids has witnessed a remarkable advancement as energy storage and conversion materials. Herein, we present an all-solid-state and scalable approach to integrate 2D-2D-type SnS2 and graphene-layered nanosheets (SnS2/G) and assessed its potential as an active material for the high-performance supercapacitor and electrocatalyst for the hydrogen evolution reaction (HER). In this in situ solvent-free strategy, a tin precursor and graphite oxide (GO) were homogeneously ball-milled with surfeit yet nontoxic elemental sulfur and subjected to a moderate thermal treatment to obtain a unique 2D-2D-type SnS2/G nanohybrid. The characterization revealed that the in situ formed SnS2 nanosheets were uniformly distributed and wrapped within graphene layers. The resulting nanohybrids demonstrated a superior specific capacitance of 565 F g-1 and retain a significant charge-discharge cyclic stability (90%/3000 cycles). Similarly, a resultant sym. device delivered a high energy d. of 23.5 Wh kg-1 and power d. 880 W kg-1 at a c.d. of 1 A g-1. Furthermore, the resulting SnS2/G nanohybrid provided a much lower HER overpotential of 0.36 V than SnS2 (0.6 V) to attain a c.d. of 10 mA cm-2 in the alk. electrolyte. The proposed strategy presents an environmentally benign avenue to integrate electrochem. active metal-sulfide-based 2D-2D-type nanostructured materials with superior energy storage and conversion capabilities.

Herein, a facile hydrothermally-assisted sonochem. approach for the synthesis of a ZnO decorated Sn3O4 nano-heterostructure is reported. The phase purity of the nano-heterostructure was confirmed by X-ray diffraction and Raman spectroscopy. The morphol. anal. demonstrated a nanosheet-like structure of Sn3O4 with a thickness of 20 nm, decorated with ZnO. The optical band gap was found to be 2.60 eV for the ZnO@Sn3O4 nano-heterostructure. Photoluminescence studies revealed the suppression of electron-hole recombination in the ZnO@Sn3O4 nano-heterostructure. The potential efficiency of ZnO@Sn3O4 was further evaluated towards photocatalytic hydrogen production via H2O splitting and degradation of methylene blue (MB) dye. Interestingly, it showed significantly superior photocatalytic activity compared to ZnO and Sn3O4. The complete degradation of MB dye solution was achieved within 40 min. The nano-heterostructure also exhibited enhanced photocatalytic activity towards hydrogen evolution (98.2μmol h-1/0.1 g) via water splitting under natural sunlight. The superior photocatalytic activity of ZnO@Sn3O4 was attributed to vacancy defects created due to its nano-heterostructure.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 814-94-8, is researched, Molecular C2O4Sn, about Morphology-dependent highly active microcrystalline stannous oxalate photocatalysts with selectively exposed facets and low specific surface areas, the main research direction is morphol microcrystalline stannous oxalate photocatalyst Methyl Orange Rhodamine B.Synthetic Route of C2O4Sn.

To achieve high photocatalytic activity, the sizes of photocatalysts are usually reduced to nanoscales. However, nano-sized particles are difficult to be separated and recycled. In this paper, we successfully fabricate stannous oxalate microcrystals with selectively exposed facets and various morphologies (prismoids, tubes, rods and needles). The photocatalytic activities are comparative or even higher than that of com. Degussa P25 nano titanium dioxide under both full spectrum light and ultra-violet irradiation, even though the stannous oxalate particles are in micrometer size. The exposure of {101} polar facets could drive photogenerated charge separation, and thus accelerates photocatalysis. The photocatalytic activities of the optimized sample (fragmented prismoids) with sp. surface areas about 1.18 m2/g are 2.49 and 2.67 times higher than that of the com. Degussa P25 nano titanium dioxide (sp. surface areas: 48.59 m2/g) under both full spectrum light and ultra-violet irradiation in methyl orange degradation, resp. The micro/submicron-sized particles could be easily separated and recycled after waste water treatment, and catalysts can be synthesized with a large amount by a facile chem. precipitation method. Given these factors, micro/submicron sized stannous oxalate catalysts are expected to be a practical water cleaner.

Compound: Tin(II) oxalate(SMILESS: O=C([O-])C([O-])=O.[Sn+2],cas:814-94-8) is researched.Electric Literature of C14H8BF4Rh. The article 《From bimetallic PdCu nanowires to ternary PdCu-SnO2 nanowires: Interface control for efficient ethanol electrooxidation》 in relation to this compound, is published in Journal of Colloid and Interface Science. Let’s take a look at the latest research on this compound (cas:814-94-8).

At present, although a large number of Pd-based nanowire electrocatalysts were prepared, there are few reports on nanowires containing rich metal oxides. Herein, porous PdCu alloy nanowires and PdCu-SnO2 nanowires were prepared by using a galvanic displacement synthesis method. Due to their 1-dimensional structure, rough surfaces with nonhomogeneous edges, electronic effect, and the advanced PdCu/SnO2 interface of the as-synthesized PdCu-SnO2 nanowire catalysts, they exhibited a mass activity of 7770.0 mA mg-1 towards EtOH oxidation, which was 7.6-fold higher than that of Pd/C catalysts (1025.0 mA mg-1). They behaved strong durability upon chronoamperometry and continuous cyclic voltammetry tests. The electrochem. measurements demonstrated that SnO2 was introduced into the PdCu/SnO2 interface, which promoted the oxidation of EtOH at a lower potential and accelerated the oxidation of Pd-COads via SnO2-OHads to regenerate the active sites. This research highlights the significance of introducing metal oxides into the nanostructure interface, and the performance of Pd-containing catalysts towards EtOH oxidation reaction was greatly improved.

HPLC of Formula: 814-94-8. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Tin(II) oxalate, is researched, Molecular C2O4Sn, CAS is 814-94-8, about Tin and Lead Alkoxides of Ethylene Glycol and Glycerol and their Decomposition to Oxide Materials. Author is Teichert, Johannes; Block, Theresa; Poettgen, Rainer; Doert, Thomas; Ruck, Michael.

A comprehensive investigation of the formation of tin and lead alkoxides with the polyalcs. ethylene glycol (C2H6O2, EG) and glycerol (C3H8O3) was conducted. Starting from tin(II) and lead(II) precursors, five alkoxides with either double- or triple-deprotonated alc. ligands were obtained. Four of them were structurally characterized by single-crystal and one by powder x-ray diffraction. The ethylene glycolates of tin(II) and lead(II), Sn(C2H4O2) and Pb(C2H4O2), show polymorphism. α- and β-Sn(C2H4O2) can be synthesized selectively by applying different reaction times. α- and β-Pb(C2H4O2), as well as Pb4(C2H4O2)4(C2H6O2), were obtained by altering the amount of NaOH and/or water used in the synthesis. With glycerol, mixed-valent tin(II,IV) glycerolate Sn5(C3H5O3)4 and lead(II) glycerolate Pb(C3H6O3) crystallized Except for Pb(C2H4O2), the obtained alkoxides are stable at ambient conditions for at least several months. The tin alkoxides were thermally decomposed in air to SnO2. A small amount of tin(II) in a SnO2 sample obtained at a low decomposition temperature was revealed by 119Sn Mossbauer spectroscopy. At the highest decomposition temperature of 800°, only tin(IV) could be detected. The morphol. of the alkoxide material is retained upon decomposition; however, the produced SnO2 consists of nanosized crystalline domains. The thermal decomposition of the lead(II) alkoxides in air yielded PbO particles with a significantly changed morphol.

Synthetic Route of C2O4Sn. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Tin(II) oxalate, is researched, Molecular C2O4Sn, CAS is 814-94-8, about Structures and electrochemical properties of Sn-Cl co-doped Li2MnO3 as positive materials for lithium ion batteries. Author is Wang, Fei; Zhai, Huan-huan; Wang, Du-dan; Li, Yu-peng; Chen, Kang-hua.

Pos. material Li2MnO3 shows the highest ratio of lithium to manganese among lithium-rich materials and exhibits the theor. capacity up to 458 mAh·g-1, making it one of the most promising cathode materials. However, this material has the intrinsic low elec. conductivity and poor cycle stability. In this paper, Li2MnO3, the lithium-rich pos. material, was prepared by sol-gel method using acetate as raw material and citric acid as a complexing agent. By using SnC2O4 as a tin source, Sn4+ instead of Mn4+ was introduced to obtain the materials with different doping amounts The resultant solution was evaporated at 80°C under vigorous stirring to get a viscous gel. Next, the resulting gel was dried at 120°C for 12 h. Finally, the gathered precursor was calcined at 600°C for 6 h under an air atm. to obtain the target material. It was found that the proper content of Sn4+ doping could increase the specific discharge capacity of the material, obtaining as high as 256.3 mAh·g-1 at low current, but had a detrimental influence on the rate performance. On this basis, SnCl2 was used for doping modification, and the Sn4+ and Cl- co-doping into Li2MnO3 revealed a better developed layered structure with high conductivity The intensity of super lattice peak formed between 2θ = 20° and 30° was increased by Cl-doping, indicating the ordered Li/Mn in the TM layer. Especially, this Sn-Cl co-doped Li2MnO3 sample delivered the relatively high specific discharge capacity of approx. 160 mAh·g-1 after 80 cycles at 20 mA·g-1. At the high c.d. of 400 mA·g-1, this material provided the specific discharge capacity of 116 mAh·g-1, which is about twice that of the undoped sample.
