Pollution-related problems in the water environment caused by nuclear wastewater leakage has attracted widespread public attention. In this study, the strategy of treating waste with waste was adopted to prepare a tea waste-derived biochar/g-C3N4/MoS2 (BgM) Z-scheme composite for the photocatalytic reduction of U(vi) in water using thermal polymerization and hydrothermal methods. Among different proportions of BGMs, 10%BgM holds the highest removal efficiency of U(vi). Approximately all U(vi) was removed by 10%BgM under air atmosphere after 2 h of light irradiation (pH = 4.5, dosage is 0.5 g L...
