摘要：

Photocatalytic overall water splitting represents a promising strategy to achieve the renewable hydrogen energy. Although Cd_1−xZn_xS catalysts show high photocatalytic hydrogen evolution efficiency in pure water, severe photocorrosion problems limit their applications. Herein, photocatalytic system composed of Co₃O₄nanoparticles anchored one-dimensional Cd_0.6Zn_0.4S nanorods (CZS/Co₃O₄) is designed and prepared by a simple hydrothermal method. Transient photovoltage tests and continuous wavelet transform analyses demonstrate that Co₃O₄nanoparticles efficiently capture the photogenerated holes to inhibit photocorrosion of CZS nanorods, accelerate surface charge transfer and prolong the lifetime of photogenerated carriers. The CZS/Co₃O₄photocatalyst exhibits high H₂and O₂evolution rates of 83.48 and 40.48 μmol h⁻¹g⁻¹, respectively. The stability is maintained over four reaction cycles without significant decrease in the absence of sacrificial agents. This work provides insight into metal sulfides against photocorrosion and extends the range of metal sulfides in solar water splitting.
