Investigation on preparation and properties of SnO2-Sb2O3-RuO2/Ti electrode

Abstract:

SnO2-Sb2O3-RuO2/Ti thin film electrode was prepared by thermal decomposition method in this paper. It is used to treat Amaranth dye simulate wastewater. The decolourization efficiency of amaranth is studied and the optimal operating conditions of the electrode are ascertained as follows: the sintered temperature is 500℃, the optimal coating layer is 6, the coating oxides proportion is n(Sn):n(Sb):n(Ru)=10:1:1. The surface morphology, microstructure, electrochemical and accelerated test shows that the surface of the SnO2-Sb2O3-RuO2/Ti electrode has the quartet rutile structure, even crystal size, good adhesion, low porosity and high catalytic-activity and long service-life .
