Modification with co-catalyst has been regarded as an effective strategy to improve the photocatalytic H₂ evolution activity of Mn_xCd_1−xS. Herein, cauliflower-like Mn_xCd_1−xS decorated with Ni₂P nanoparticles has been prepared via solvothermal method. Experiment results confirmed that modification with Ni₂P could promote charge transfer efficiency and boost surface reaction rate of Mn_xCd_1−xS. The superior activity of 14.20 mmol g⁻¹h⁻¹ was obtained over the 3 wt% Ni₂P/Mn_0.2Cd_0.8S composite, which was approximately an 8.3-fold enhancement over pure Mn_0.2Cd_0.8S. Furthermore, the activity over Mn_0.2Cd_0.8S modified with Ni₂P was higher than other Ni-based co-catalysts (Ni, Ni₂S, Ni(OH)₂, NiB and NiSe₂) modification. This work offers a new perspective to design highly efficient photocatalytic system towards H₂ evolution.
