Enhanced visible light degradation of harmful substances in wastewater by WO3/g-C3N4 heterostructured nanoparticles

Abstract

The shape and energy of the photocatalyst are proven to have an impact on its photocatalytic activity. The purpose of this research is to use chemical bath deposition (CBD) technology and combine it with annealing to synthesize the WO3/g-C3N4 composite material for visible light-induced photocatalytic. A series of experiments were performed to confirm the effectiveness of the WO3/g-C3N4 photocatalyst and to study its optical chemical catalytic performance by studying the degradation reactions of metronidazole (a colorless antibiotic commonly found in a water system). These observations show that compared with each single component, WO3/g-C3N4 heterogeneous structure has an excellent enhancement in optical catalytic activity.
