m.基催化剂在电催化析氢反应（HER）中具有巨大应用潜力.然而,其活性位点的暴露不足、极强的氢吸附能力导致其催化性能未能充分体现.本文在碳布上构筑了m.2N–m.Se2异质结（m.S）,以增强m.基催化剂的HER活性.由于m.S中的m.2N具有较低的功函数,能够在异质界面产生内建电场,显著提高了其在HER中电荷转移效率.此外,m.S中原子之间的强电子相互作用优化了m.位点的电子结构,降低了氢吸附能力,进一步增强了其本征催化活性.因此, m.S催化剂产生20 m.a.cm.2和1 a.cm.2的析氢电流密度所需的过电位仅为65和210 m., Ta.el斜率仅为96 m. dec-1.此外, m.S在1 a.cm.2电流密度下稳定运行240小时后,形貌、结构和性能均无明显变化.以上研究结果为工业大电流制氢所需的非贵金属基电催化剂的设计和合成提供了新思路.
