Two-dimensional(2D)transition metal dichalcogenides(TMDs)have emerged as promising alterna-tives to the platinum-based catalysts for hydrogen evolution reaction(HER).The edge site of these 2D materials exhibits HER-active properties,whereas the large-area basal plane is inactive.Therefore,recent studies and methodologies have been investigated to improve the performance of TMD-based materials by activating inactive sites through elemental doping strategies.In this review,we focus on the metal and non-metal dopant effects on group Ⅵ TMDs such as MoS2,MoSe2,WS2,and WSe2 for promoting HER performances in acidic electrolytes.A general introduction to the HER is initially provided to explain the parameters in accessing the catalytic performance of doped-TMDs.Then,synthetic methods for doped-TMDs and their HER performances are introduced in order to understand the effect of various dopants including metallic and non-metallic elements.Finally,the current challenges and future opportunities are summarized to provide insights into developing highly active and stable doped-TMD materials and valuable guidelines for engineering TMD-based nanocatalysts for practical water splitting technologies.
