Improving the photocatalytic activity of TiO2 by accelerating interfacial carrier kinetics using Ti3C2 and CoP as co-catalysts

This study initially involved the initial creation of a CoP/TiO2 p-n Schottky junction by combining TiO2 with the narrow band gap semiconductor CoP. Subsequently, the CoP/TiO2 composite was grown in situ on Ti3C2 through electrostatic self-assembly, resulting in a 2D ternary structural Ti3C2/CoP/TiO2 composite featuring dual co-catalysts CoP and Ti3C2.

本研究首先将二氧化钛（TiO2）与窄带隙半导体磷化钴（CoP）相结合，构建了CoP/TiO2型p-n肖特基结（Schottky junction）。随后，通过静电自组装策略在Ti3C2表面原位生长CoP/TiO2复合物，最终得到兼具双助催化剂CoP与Ti3C2的二维三元结构Ti3C2/CoP/TiO2复合物。
