Abstract
Loading co-catalyst is one of the essential ways to strengthen the performance of photocatalyst. Here, a novel non-precious metal co-catalyst Ti2C/TiO2 was successfully synthesized and Zn0.5Cd0.5S nanoparticle grown on the surface of Ti2C/TiO2 equably. In our work, 0.01 g photocatalysts were used in photocatalytic activity measurement. Zn0.5Cd0.5S/Ti2C/TiO2 composite (2 wt% Ti2C/TiO2) exhibited the highest photocatalytic activity and the H2 yield is 32.57 mmol/gâ1/hâ1 under visible light irradiation. The photoelectrochemical results reveal that Ti2C/TiO2 could improve the separation of the photo-induced carriers in Zn0.5Cd0.5S/Ti2C/TiO2 heterojunction. And DFT calculations demonstrate that the Gibbs free energy of oxygen-terminated Ti2C and TiO2 are much lower than that of Zn0.5Cd0.5S. Therefore, the Ti2C/TiO2 has an active impact on improving the H2 production of Zn0.5Cd0.5S. This study provides a new way to explore the application of inexpensive co-catalysts on a large scale.
