A series of p-n coupled p-CoFe₂O₄/n-CdS photocatalysts were prepared by a hydrothermal method. The structure and properties of p-CoFe₂O₄/n-CdS were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), transmission electron microscopy (TEM) and the electrochemical workstation. The photocatalytic activities of p-CoFe₂O₄/nCdS were evaluated by photocatalytic hydrogen production under visible light irradiation. The effects of photocorrosion of CdS in p-CoFe₂O₄/n-CdS were investigated by analyzing the cadmium concentration of the supernatant collected after the photocatalytic reactions. The mechanism of the catalytic activity enhancement, effects of reaction conditions on the photocatalytic hydrogen evolution rate, and cadmium leakage resistance are discussed. The results show that p-CoFe₂O₄/n-CdS exhibits higher photocatalytic activity attributed to stronger light absorption by the two types of narrow band gap semiconductor CoFe₂O₄ and CdS, the formation of a "forest-like" structure of CdS and rapid electron transfer from CoFe₂O₄ to CdS, resulting from band overlap and an inner electric field in p-CoFe₂O₄/n-CdS, to reduce the probability of electron/hole pair recombination. Both the separation efficiency of photo-generated electron-hole pairs and the adsorption performance of photocatalysts had an important influence on the hydrogen production rate. The pH of the CH₃OH aqueous solution influenced the separation efficiency of photogenerated electron-hole pairs and the adsorption properties of the photocatalyst. p-CoFe₂O₄/n-CdS also exhibited resistance against cadmium leakage under light irradiation owing to the presence of methanol in the reaction solution, the band overlap of the semiconductors and the inner electric field in p-CoFe₂O₄/n-CdS. The band overlap and inner electric field had the most influence on the cadmium leakage resistance.
