abstract = "With giving property to guide and control charge carries at the nanoscale, fabrication of heterostructure photocatalyst with desirable spatial distribution has been significantly valued. In this study, by using CuS nanoplates as seeds, CuS@ZnS coreshell heterojunction photocatalysts
with diverse morphologies were developed via controlled synthesis kinetics. Kinetic control was completed through manipulation of the injection rate of Zn2+ precursor with a syringe pump as well as the reaction temperature. It is found that the growth is determined by the deposition
rate relative to the diffusion rate of the ZnS growth monomers. Specifically, at a high injection rate and a relatively low reaction temperature, ZnS monomers on the surface of the CuS nanoplate will be in a localized manner and tend to form island nanoparticles. On the contrary, when surface
diffusion is facilitated at a lower injection rate and a higher reaction temperature, the morphology of the ZnS nanocrystals can be switched to flat ZnS layers covering the surface of CuS. In addition, the heterostructures have found with shape-dependent photocatalytic performance toward H2
evolution under visiblelight irradiation. The CuS@ZnS coreshell composites that possess ZnS islands exhibit the highest photocatalytic activity. The corresponding H2 generation rate reaches 6.3 mol h1 g1, which is 37.9 times
of that for CuS@ZnS coreshell nanostructure with flat surface. This work thus provides a powerful means for the rational design and synthesis of heterojunctions with spatially controlled distribution of the component.",
