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.
