Abstract
Having an insight into the optimizations of intrinsic properties of cocatalysts via doping foreign atoms to promote solar-driven water splitting into hydrogen (H2) energy conversion is increasingly important, but it remains a challenging scheme. Herein, zero-dimensional/one-dimensional (0D/1D) structured TMCoSe/CdS0.95Se0.05 was successfully synthesized through a two-pot hydrothermal treatment. Experimental results show that the FeCoSe/CdS0.95Se0.05 photocatalyst exhibits the most excellent photocatalytic H2 evolution performance (513.76 μmol h−1), which is 36.6 times and 2.0 times higher than that of CdS0.95Se0.05 and the optimal CoSe/CdS0.95Se0.05, respectively. In addition, photochemical and photoluminescence results reveal that the FeCoSe/CdS0.95Se0.05 sample shows the most rapid carrier dynamics among all samples. Theoretical calculations demonstrate that the excellent activity of FeCoSe/CdS0.95Se0.05 nanocomposite can be attributed to the formation of Schottky-type heterojunction between semi-metallic FeCoSe cocatalyst and CdS0.95Se0.05, which can enhance the efficiency of charge carrier separation and utilization, thus promoting the H2-generation performance.
