摘要

在此基础上，引入Zn来调节Co3O4的四面体配位，然后通过碱浸浸出。实验表征表明，四面体缺陷的生成显著提高了电催化析氧反应（OER）活性。理论计算表明，这些选择性缺陷使吸附位点具有适度的d带中心，从而优化了中间体的结合强度。

Constructing cation defects through selective etching of tetrahedral sites in Co3O4 for an enhanced oxygen evolution reaction†

Herein, Zn was introduced to regulate the tetrahedral coordination of Co₃O₄ and then leached out via alkaline impregnation. Experimental characterization indicated that the generation of tetrahedral defects significantly enhanced the electrocatalytic oxygen evolution reaction (OER) activity. Theoretical calculations showed that these selective defects endowed the adsorption sites with a moderate d-band center, thus optimizing the binding strength of intermediates.
