Electrocatalytic decomposition of water is an effective method to solve the energy and environmental crisis brought about by fossil fuel combustion. Due to its low cost and abundant resources, non-precious metal catalysts have achieved rapid development and are widely used in the electrolysis of water. Among these catalysts, WS 2 is known as a potential candidate for water decomposition catalysts because of its unique physical and chemical properties and crystal structure. Therefore, we summarize the application of WS 2 in the field of electrolysis water splitting. First, the crystal structure, the principle of HER/OER, and the performance evaluation parameters are introduced. Then it focuses on the preparation and structure control of WS 2 , the method, and the mechanism of performance optimization. Finally, the research on theoretical calculations of WS 2 and a discussion about the opportunities and challenges of WS 2 as electrocatalyst in the future are summarized. To improve the readability of this review, a concise overview at the end of each section gives some of the characteristics and trends of the studies in the corresponding part.
