Recent years, nanomaterials have attracted enormous attention due to their nano-size effect and a wide range of applications in various fields, such as environmental remediation, medicine, and bioengineering. Special attention has been placed to the study of the adsorption ability of nanomaterials because of their outstanding advantages, such as large specific surface area and high surface energy, and so on. Metal sulfide nanomaterials, which are regarded as one of the most promising candidates owing to their advantages of fast adsorption speed, high adsorption capacity and excellent adsorption stability, have shown extraordinary adsorption capacity to heavy metals, radioactive elements and organics in aqueous solution and soil, promoting their great research and application prospects. This review summarizes the research progress of several types of metal sulfide nanomaterials, including ZnS, iron sulfides, MoS₂, CuS and other metal sulfides, as well as their related composite materials in the field of adsorption. In the end, the future research prospects are suggested.
