In recent years, transition metal sulfides have been widely studied in the context of their use as electrocatalysts. The electrocatalytic propensity of the classical semiconductor MoS , which exists in the 1T and 2H phase structures, has attracted extensive attention. Therefore, the synthesis of highly active and stable MoS -based catalysts has become the goal of many research efforts. We recently developed a method that can be utilized to prepare the MoS /MoO heterojunction in a phase-controlled manner. 1T-MoS phase enriched MoS /MoO heterojunction can be generated using a simple hydrothermal and acid treatment sequence and that the heterojunction has a unique three-dimensional structure, large active surface area, and therefore achieve a low overpotential and high catalytic current density, as well as long-term stability for the hydrogen evolution reaction.
近年来，过渡金属硫化物作为电催化剂的应用受到了广泛研究。存在于1T和2H相结构中的经典半导体MoS₂的电催化性能引起了广泛关注。因此，合成高活性和稳定的MoS₂基催化剂已成为许多研究工作的目标。我们最近开发了一种方法，可用于以相控方式制备MoS₂/MoOₓ异质结。通过简单的水热和酸处理序列可以生成富含1T-MoS₂相的MoS₂/MoOₓ异质结，并且该异质结具有独特的三维结构、大活性表面积，因此实现了低过电位和高催化电流密度，以及析氢反应的长期稳定性。
