Construction of BPQDs/Ti₃C₂@TiO₂ Composites with Favorable Charge Transfer Channels for Enhanced Photocatalytic Activity under Visible Light Irradiation.

ABSTRACT: Design and construction of double heterojunction is favorable to improve the separation and migration efficiency of photogenerated carriers, thus preferably solve the problems of environmental pollution and energy crisis. Herein, TiO₂ nanoparticles (NPs) are in-situ grown on highly conductive Ti₃C₂ nanosheets via low-temperature hydrothermal strategy, and then black phosphorus quantum dots (BPQDs) are introduced on the surface of TiO₂ NPs. Under hydrothermal temperature 120 °C, the BPQDs/Ti₃C₂@TiO₂ photocatalyst exhibits remarkable enhanced photocatalytic degradation of methyl orange (MO) and hydrogen evolution reaction (HER) compared with BPQDs/Ti₃C₂ and Ti₃C₂@TiO₂
