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.
When you point to this article, it is believed that you are also very interested in this compound(814-94-8)Synthetic Route of C2O4Sn and due to space limitations, I can only present the most important information.
