【 摘 要 】

CoSe_2, as a kind of co-catalyst, would replace noble metals element to dope pure CdS. The CoSe₂/CdS photocatalyst could be synthesized by simple physical mixing. With the introduction of CoSe₂, especially 30% CoSe₂/CdS, hydrogen production would be about 500 μmol within 5 h, five times that of pure CdS under the same conditions. The CoSe₂/CdS photocatalyst could bear four cycles of hydrogen evolution and sustain the hydrogen production, with a minor decrease. In other words, the electron transition velocity would surge along with the introduction of CoSe₂ particles. The CoSe₂ could be deemed as the predator and exit of electrons to inspire the detachment of the hole-electron pairs and relieve the recombination of the hole-electron pairs.
