Z-scheme photocatalysis water splitting system is an effective approach to integrate the advantages both hydrogen evolution photocatalyst and oxygen evolution photocatalyst. The interfaces property of the heterojunctions has a great influence on the efficiency through the crystal orientation and the charge kinetics. In this study, general chemical vapor deposition process and gentle cation-exchange method were combined successively to smart design and flexible assemble the Z-scheme photocatalysts between CdS and MnS. Owing to the well-defined heterojunctions interfaces and distinctive structural benefits, the one dimension CdS/MnS hybrid photocatalysts without any co-catalysts exhibited the significantly increased photocatalytic H 2 evolution rate of 1595 μmol h -1 g -1 (apparent quantum efficiency of 22.6% at 420 nm), which is over 10.5 times higher than that of original CdS. Moreover, good photocatalytic stability also be demonstrated over particulate (42 h cycling measurement) and photoelectrochemical (3000 min continuous measurement) systems. Overall, this work provides unique experimental insight into the high-quality heterojunctions interface design and novel Z-scheme photocatalysts synthesis.
