The Microwave Synthesis and Photocatalytic Activity of InVO4 Nanocrystalline

Article Preview

Abstract:

Indium vanadate nanocrystalline was prepared by Indium chloride, vanadium (V) oxide as raw materials and sodium dodecyl sulfate as surfactant under microwave irradiation. The sample was characterized by X-ray diffraction (XRD), scanning electron micrograph (SEM). We studied the photocatalytic activity of the as-prepared samples using degradation of methyl orange in visible light. It shows that the photocatalytic activity of Indium vanadate nanocrystalline was very well. It found that when the catalyst calcined at 773 K was 0.10 g, and 0.3 mL hydrogen peroxide joined as well as pH was 2.0, the degradation ratio of InVO4 for methylene orange of 100 mL 2 mg/L reached 75% in 50 min.
