摘要
二硫化钼(MoS_(2))纳米片是一种典型的二维材料,因其独特可调的电子结构和优异的氢气析出反应(HER)电催化活性受到研究者的广泛关注.为了进一步提高其电催化性能,科学家深入研究反应的微观机理,以期阐明材料电子结构中影响电催化性能的关键因素,构建合理的电子描述符.本文综述了近年来d带中心理论探究MoS_(2)电催化HER机理的起源、发展和现状,以期为该类催化剂的进一步发展提供指导.
Molybdenum disulfide(MoS_(2))nanosheets,a typical two-dimensional material,have received much attention for its unique tunable electronic structure and excellent electrocatalytic activity for hydrogen evolution reaction(HER).In order to further improve its electrocatalytic performance,in-depth investigations on microscopic HER mechanism have been conducted to elucidate the key factors influencing the electrocatalytic performance within the material's electronic structure and construct reasonable electronic descriptors.This paper reviews the origin,development and current status of the d-band center theory to probe the mechanism of MoS_(2) electrocatalytic HER in recent years,with a view to providing guidance for the further development of this type of catalyst.
