Research.The visible light catalytic system an of efficient stable is constructed other than electronic structure to be considered, it is also noted that material category, shape
The influence of the properties such as looks structure, crystallinity and surface characteristic.The selection of material is even more important, because it determines semiconductor material
Visible light-responded degree and gross efficiency.MSnO3(M=Zn, Ca, Sr, Ba and Ag) and Zn2SnO4As a kind of important ternary oxygen
Compound is widely used in gas sensitive, electronic device, fire retardant, lithium ion battery and catalysis material etc., photoproduction e--h+'s
Mobility then determines catalytic activity and quantum yield, it is considered that the process and crystal bulk structure and degree of crystallization, surface
The microscopic surface textures such as product, co-catalyst are closely related.Wherein, zinc stannate (ZnSnO3), peace good, nontoxic with thermal stability
Entirely, it easily uses and feature that flame retarding efficiency is high, and there is preferable optical property.Therefore, development can efficiently use nature too
The nanometer ZnS nO of sunlight3Photochemical catalyst, for expanding the work of available nano-photocatalyst material and nano photo catalyzed oxidation
Industry application range saves wastewater treatment energy consumption, is of great immediate significance and far reaching significance.
