The Microwave Synthesis and Photocatalytic Activity of Silver Vanadate

Abstract:

Using one simple microwave synthesis method, take silver nitrate and vanadium(V) oxide as raw meterial to synthesize Silver Vanadate. The photocatalytic degradation of methyl orange under visible light irradation showed that the photocatalytic activities of microwave synthetic samples were better than those of samples produced by conventional hydrothermal technique. This experiment is to discuss the impact of these factors upon the catalyst performance through the control of the calcine temperature, the quantity of hydrogen peroxide, pH, the concentration of methyl orange and the quantity of catalyst. When the catalyst was calcined at 500 °C ,0.1 g, and 0.5 mL hydrogen peroxide joinded as well as pH was 2.0, the degradation ratio of Ag3VO4 for methyl orange of 100 mL 5 mg/L reached 91.49％ in 40 min.
