In this work, MnCo2S4/CdS type-I nanorod heterojunctions were successfullynconstructed, and the stability of the structure and photocatalyticnperformance of the composites were significantly improved by the timelyntransfer of photogenerated holes on the valence band and photogeneratednelectrons on the conduction band of CdS through the discontinuousnMnCo2S4 grown outside the nanorods. The photocatalyticnhydrogen production of 5% loaded MnCo2S4/CdSnunder visible light (λ ≥ 420 nm) can reach 12 mmol·g–1·h–1, which is 42 times morenefficient than the hydrogen production of pure CdS nanorods in thenpresence of Na2S and Na2SO3 as holenscavengers.
