Rapid urbanization and growing population have led to an increase in the consumption of resources, resulting in water pollution and energy shortage, calling for advanced solutions. For that, transition metal chalcogenides have gained interest because of their earth abundance, tunable bandgaps, modifiable elemental composition, catalytic stability, visible light activity and optoelectrical properties. Here, we review the history, basics, preparation, characterization and environmental applications of transition metal chalcogenides. Methods are hot-plate, solvothermal and hydrothermal, one-pot heat-up and electrospinning. Applications include adsorption, photocatalysis, electrocatalysis, dye-sensitized solar cells and antimicrobials. Transition metal chalcogenide are compared with traditional nanomaterials.

快速城市化和人口增长导致资源消耗增加，导致水污染和能源短缺，需要先进的解决方案。为此，过渡金属硫属化物因其地球丰度、可调谐带隙、可改变元素组成、催化稳定性、可见光活性和光电特性而受到关注。在这里，我们回顾了过渡金属硫属元素化物的历史、基础、制备、表征和环境应用。方法是热板、溶剂热和水热、一锅加热和静电纺丝。应用包括吸附、光催化、电催化、染料敏化太阳能电池和抗菌剂。过渡金属硫属化物与传统纳米材料相比。
