In this study, a highly efficient Ti3CN@TiO2/CdS photocatalyst was reported. Ti3CN@TiO2 materials with different morphologies were obtained from Ti3AlCN by controlling the etching time, and CdS nanoparticles were loaded onto the catalyst to improve its photocatalytic efficiency.
Solar energy to hydrogen production is an effective way to solve the energy crisis. Here, we report a Ti3CN@TiO2/CdS photocatalyst with highly efficient photocatalytic performance. Ti3CN@TiO2 materials with nanoflower morphology or lamellar morphology were obtained from Ti3AlCN by controlling the etching time, and then loaded CdS nanoparticles to improve the photocatalytic efficiency. The physical and chemical properties of the catalyst were characterized by various characterization techniques. Ti3CN@TiO2/CdS photocatalyst shows an enhanced photocatalytic activity of 3393.4 mmol g(-1)h(-1), much higher than that of CdS and Ti3CN@TiO2. (C) 2021 Hydrogen Energy Publications LLC.
