Abstract: The functional performance of the inorganic nano-materials was impacted by many factors，such as the crystal structure，dimensions，morphology，particle size，etc. CdS，ZnS，and their composites have special properties in optical，electrical，magnetic，catalytic，and mechanical aspects，which are closely related to their crystalline forms and morphologies. Preparation of sulfide-based semiconductor nanomaterials with controlled particle size，shape，crystallite orientation，and study on the effect of structure and morphology on photocatalytic properties are of great significance in the development of new highly efficient photocatalytic materials. The recent results of the shape-controlled synthesis of the sulfide-based photocatalysts are summarize for water splitting and organic dye degradation in this paper. The morphology of sulfide-based photocatalysts includes nanowires，nanorods，spherical，leaf shape，flower and etc. Synthesis methods of the sulfide-based catalysts can be divided into the following categories：template method，hydrothermal，solvothermal，precipitation，sol-gel method，etc. The methods for controlling the particle morphology mainly include：①control of the crystal nucleation and growth，②control of the reaction conditions，③template aggregation and④application of surfactants. The effect of the catalyst morphology on the photocatalytic activity of the sulfide-based photocatalysts was discussed. Current problems and future perspectives for the shape-controlled synthesis of sulfide-based photocatalysts were also indicated in the paper.
