Abstract Low-cost Ni modified CdS was prepared via a hydrothermal reduction method. The hydrogen production activity of CdS loaded with 5 wt% Ni under visible light was even higher than that of the one loaded with 0.5 wt% Pt. The highest H 2 evolution rate (3004.8 μmol h −1 ) occurred when the concentration of sacrificial agent (lactic acid) was 50 vol%. The nickel can quickly transfer excited electrons and enhance the photocatalytic H 2 production activity. It was also found that the hydrogen evolution in this system was generated steadily from both water and lactic acid.

CdS负载镍对乳酸溶液光催化制氢的促进作用

摘要 采用水热还原法制备了低成本的Ni改性CdS。在可见光下负载 5 wt% Ni 的 CdS 的产氢活性甚至高于负载 0.5 wt% Pt 的产氢活性。当牺牲剂（乳酸）的浓度为 50 vol% 时，H 2 的释放速率最高（3004.8 μmol h -1 ）。镍能快速转移受激电子，提高光催化产氢活性。还发现该系统中的析氢是由水和乳酸稳定产生的。
