Fabrication of Ag3PO4 /g-C3N4 composite: enhanced charge separation and outstanding photoactivity under very low intensity visible light irradiation
A visible light driven Ag3PO4/g-C3N4 composite photocatalyst was synthesized by a simple coprecipitaion method by changing the loadings of g-C3N4 for degradation of methyl orange (MO) dye under very low visible light intensity. The results revealed that the introduction of g-C3N4 onto Ag3PO4 surface...

| Summary: | A visible light driven Ag3PO4/g-C3N4 composite photocatalyst was synthesized by a simple coprecipitaion method by changing the loadings of g-C3N4 for degradation of methyl orange (MO) dye under very low visible light intensity. The results revealed that the introduction of g-C3N4 onto Ag3PO4 surface greatly improved its stability and photocatalitic activity. It was found that Ag3PO4/g-C3N4 with mass ratio Ag3PO4:g-C3N4 of 1:0.03 exhibited 98% of degradation under 20 minutes of irradiation time. The study proved that h+ played the chief role in the degradation process and a possible heterojunction mechanism was proposed. |
