对 18 种不同的 IVB-VIB 过渡金属碳化物、氮化物、硫化物、硅化物和硼化物以及三种主族元素陶瓷 AlN、B4C 和 h-RN 的析氢反应 (HER) 电催化性能进行了系统的比较研究。我们利用固定颗粒的伏安法作为一种可以快速筛选和表征电催化剂的方法。电催化剂的性能（通过 100 mM H2SO4 中析氢反应的过电势）与铂和镍作为基准进行了比较。尽管所研究的催化剂材料在过电势和稳定性方面都没有达到铂的性能，但几种化合物（即碳化钨和钼以及硼化钨）的电催化性能需要持续的研究。 (C) 2012 Elsevier B.V. 保留所有权利。
A systematic and comparative investigation of 18 different IVB-VIB transition metal carbides, nitrides, sulfides, suicides and borides as well as of the three main group element ceramics AlN, B4C and h-RN for their electrocatalytic performance towards the hydrogen evolution reaction (HER) is presented. We exploited the voltammetry of immobilised particles as a method that allows a rapid electrocatalyst screening and characterisation. The performances of the electrocatalysts - by means of the overpotential of the hydrogen evolution reaction in 100 mM H2SO4 - were compared with platinum and nickel as benchmarks. Although none of the catalyst materials investigated reached the performance of platinum with respect to overpotential and stability, the electrocatalytic properties of several compounds, i.e. tungsten and molybdenum carbide but also of tungsten boride calls for continuative work.
