Zinc stannate, covering ZnSnO3 and Zn2SnO4 and commonly called zinc tin oxide (ZTO), is a class of ternary oxides with high electron mobility, high electrical conductivity, attractive optical properties and greater stability than its binary counterparts such as ZnO and SnO2[1][2][3]. ZTO serves as a sensing element: ethanol and other reductive gases react with oxygen species adsorbed on its surface, raising the resistance, and porous zinc stannate structures have been applied to gas sensing[2][3].
ZnSnO3 is used as a catalyst in organic synthesis, fuel cells and photocatalysis, while Zn2SnO4 serves as a photocatalyst for dye photodegradation, photocatalytic H2 generation, CO2 photoreduction and photocatalytic removal of gaseous pollutants[2]. | [Flammability and Explosibility]
Notclassified | [Synthesis]
Zinc stannate compounds are prepared by solid-state reaction of ZnO and SnO2 in stoichiometric molar ratios (2:1 for Zn2SnO4, 1:1 for ZnSnO3), with SnO2 supplied either as a chemical precursor or as naturally occurring cassiterite mineral, and calcination up to 1100 °C; during crystallization the metastable ZnSnO3 formed at 300–500 °C converts into the stable Zn2SnO4 above 600 °C[1]. Zn2SnO4 nanoparticles are also obtained by one-step mechanochemical processing, in which ZnO and SnO2 precursors in a 2:1 molar ratio are milled and calcined at 1100 °C for 24 h and sintered at 1100 °C[1]. | [References]
