Abstract

Graphical abstract: Highlights: Cu-MOF/rGO cocatalyst was applied to synthesis novel Ag3 VO4 /Cu-MOF/rGO nanocomposite. Reduced graphene oxide was used as the charge carrier from Ag3 VO4 to Cu-MOF. Experimental results demonstrate demonstrated that O 2 - is the major reactive species in dye degradation. Abstract: Cu-based metal organic framework/rGO was used as an effective cocatalyst to synthesis novel Ag3 VO4 /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 Ag3 VO4 /Cu-MOF/rGO nanocomposite indicated significant improved activity compared with pure Ag3 VO4 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.
