Visible light production of hydrogen from glycerol over Cu2O-gC3N4 nanocomposites with enhanced photocatalytic efficiency

In this work, we investigate nanostructured Cu2O-gC3N4 composites with diverse Cu2O addition (0.5–3.0 mol %) prepared by ultrasonication-mixture of mesoporous Cu2O and g-C3N4 prepared individually from soft and hard-template sol–gel, respectively. The efficiency of the Cu2O-gC3N4 nanocomposites depends on the Cu2O/gC3N4 ratio because it controls the heterojunctions development between them. The synergistic influence amid Cu2O and g-C3N4 in the...
