Abstract:
A novel BiVO 4 /Cu/g‐C 3 N 4 heterostructure photocatalyst was synthesized by thermal condensation, hydrothermal, and in situ precipitation method. The microscopic morphology and chemical composition of the synthesized samples were analyzed by XRD, SEM, FT‐IR, XPS, and other characterizations. BiVO 4 /Cu/g‐C 3 N 4 (BiVO 4 /Cu:g‐C 3 N 4 mass ratio was 1:1) photocatalyst had the optimal photocatalytic degradation activity for tetracycline (TC) wastewater under visible light irradiation (120 min, 74.8%). The introduction of Cu and Z‐scheme heterojunction was further confirmed by UV‐vis, PL, EIS, and capture mechanism analysis, which effectively accelerated the separation and transfer rate of photogenerated electron holes and enhanced the strong oxidation of h + and •O 2 − active species. BiVO 4 /Cu/g‐C 3 N 4 heterojunction photocatalytic material has potential application value in the removal of refractory pollutants in wastewater. Practitioner points A novel Z‐scheme BiVO 4 /Cu/g‐C 3 N 4 photocatalyst with excellent photocatalytic activities and stability was prepared to treat tetracycline (TC) wastewater. 1:1 CBCN (BiVO 4 /Cu:g‐C 3 N 4 mass ratio was 1:1) photocatalyst exhibited the highest photocatalytic performance for TC wastewater. The Z‐scheme heterojunction and Cu act as the interfacial charge transfer medium accelerated the transfer and separation of carriers.
