Synthesis and Photocatalytic Property of Cu₃V₂O₈ Prepared by Liquid Phase Precipitation

Abstract:

Cu₃V₂O₈ powder was prepared by the liquid phase precipitation method and characterized using XRD , SEM and BET. The photocatalytic decolorization of methyl orange in Cu₃V₂O₈ powder suspension was investigated using 20w UV light as light source．The result shows that the the liquid-phase precipitation method is a simple and effective method for Cu₃V₂O₈ powder preparation. It was found that the sample prepared with the n(V)/n(Cu)moral ratio be 2/3, pH=7 and calcinated under 750°C for 4 hours was pure triclinc Cu₃V₂O₈ phase.
