Main-Group Nonmetal Single-Selenium-Atom Electrocatalysts for Alkaline Hydrogen Evolution
Herein, we report a scalable strategy to fabricate nitrogen-doped carbon containing nonmetal selenium (Se) single atoms (SAs), termed Se SA/NC, by hydrogen bonding and subsequent calcination. The Se SA/NC loading 3.2 wt % Se SAs displays the best electrocatalytic activity, as well as excellent stability for alkaline hydrogen evolution reaction (HER), which is superior or at least comparable to the reported noble metal-based electrocatalysts. The experimental and theoretical studies reveal that the Se SAs at a lower loading can largely lower the reaction barrier for remarkably enhanced alkaline HER. This research provides a feasible strategy for designing high-performance nonmetal SAs for HER.
