Investigation the Role of Cu-MOF/rGO in Improvement of Catalytic Performance of Ag3VO4

In recent years, photocatalysis over semiconductor materials has been widely studied as a promising strategy for solar energy alteration and solving environmental problems [1, 2]. Along with other semiconductors, Ag based photocatalysts have been attracted attention due to their great visible light response [3]. In present study, Cu-based metal organic framework/rGO was used as an effective cocatalyst to synthesis novel Ag3VO4/Cu-MOF/rGO nanocomposite. The resulting photocatalysts were characterized by different microscopic and spectroscopic methods. The photocatalytic degradation studies on acid blue 92 showed that Ag3VO4/Cu-MOF/rGO nanocomposite indicated significant improved activity compared with pure Ag3VO4 and Cu-MOF/rGO. The improved photocatalytic activity of nanocomposite was attributed to the increased surface area and effective charge carrier separation and transport in the nanocomposite.
