Facile deposition of transition metal boride (TMB) with high‐boron content as highly efficient hydrogen evolution reaction (HER) electrocatalyst has been realized by a facile one‐step electroless‐plating (EP) method. Boron content of the TMB catalyst shows an appreciable impact on its intrinsic HER activity. NiB/NF electrode with thin amorphous nickel boride (NiB) deposition on nickel foam (NF) required overpotential of only 41.2 mV to deliver a current density of 10 mA cm⁻² for HER in 1.0 M KOH alkaline electrolyte. Meanwhile, this kind of electrode also shows satisfied stability which can work at large current density of 1000 mA cm⁻² for over 72 h without performance degradation. The advance on the TMB electrode may pave a way to the development of practical electrodes for water splitting.

高硼含量过渡金属硼化物的化学镀作为高级HER电催化剂

通过简便的一步式化学镀（EP）方法已经实现了高硼含量过渡金属硼化物（TMB）的快速沉积，作为高效的析氢反应（HER）电催化剂。TMB催化剂的硼含量对其固有的HER活性显示出显着的影响。在1.0M KOH碱性电解液中，用于HER的电流密度仅为41.2 mV，以在HER中提供10 mA cm ^-2的电流密度，而在镍泡沫（NF）上沉积有薄的非晶态硼化镍（NiB）的NiB / NF电极。同时，这种电极还显示出令人满意的稳定性，可以在1000 mA cm ^-2的大电流密度下工作持续72小时以上，而性能不会下降。TMB电极的进步可能为开发用于水分解的实用电极铺平了道路。
