开发在所有pH条件下有效操作的有效非贵金属析氢反应(HER)电催化剂是高度期望的,但仍然是具有挑战性的任务。本文通过将相应的WO 3 NA/CC前驱体用NH3氮化,在碳布上制备了氮化钨纳米棒阵列(WN NA/CC),作为一种高效的三维析氢阴极,在酸性溶液中具有很强的耐久性。它需要198 mV的过电位才能达到10 mA cm− 2的电流密度,并保持其催化活性至少60 h。该电极在中性和碱性条件下也表现良好。此外,该电极在所有pH值下显示出接近100%的法拉第效率。
It is highly desired but still remains a challenging task to develop efficient non-noble-metal hydrogen evolution reaction (HER) electrocatalysts operating efficiently under all pH conditions. In this paper, tungsten nitride nanorods array was developed on carbon cloth (WN NA/CC) through nitridation of corresponding WO3NA/CC precursor with NH3as an efficient 3D hydrogen evolution cathode with strong durability in acidic solutions. It needs overpotential of 198 mV to achieve current density of 10 mA cm−2and it maintains its catalytic activity for at least 60 h. This electrode also performs well under both neutral and alkaline conditions. In addition, this electrode shows nearly 100% Faradaic efficiency at all pH values.
