摘要

在此，我们报告了一种可扩展的策略，通过氢键和随后的煅烧来制备含非金属硒（Se）单原子（SAs）的氮掺杂碳，称为Se SA/NC。Se SA/NC负载3.2 wt % Se SA表现出最好的电催化活性，以及良好的碱性析氢反应（HER）稳定性，优于或至少与报道的贵金属基电催化剂相当。实验和理论研究表明，在较低的负载下，Se - sa可以显著降低碱性HER的反应势垒。本研究为设计高性能的HER非金属sa提供了可行的策略。

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.

期刊介绍： Inorganic Chemistry publishes fundamental studies in all phases of inorganic chemistry. Coverage includes experimental and theoretical reports on quantitative studies of structure and thermodynamics, kinetics, mechanisms of inorganic reactions, bioinorganic chemistry, and relevant aspects of organometallic chemistry, solid-state phenomena, and chemical bonding theory. Emphasis is placed on the synthesis, structure, thermodynamics, reactivity, spectroscopy, and bonding properties of significant new and known compounds.
