Synthesis and characterization of g-C3N4/Cu2O composite catalyst with enhanced photocatalytic activity under visible light irradiation
Source abstract
Abstract
Abstract To overcome the drawback of low photocatalytic efficiency brought by electron–hole pairs recombination and narrow photo-response range, a novel g-C 3 N 4 /Cu 2 O composite photocatalyst was designed and prepared successfully. Compared with bare Cu 2 O and g-C 3 N 4 , the g-C 3 N 4 /Cu 2 O composite exhibited significantly enhanced photocatalytic activity for acid orange-II (AO-II) degradation under visible light irradiation. Based on energy band positions, the mechanism of enhanced visible-light photocatalytic activity was proposed.
