摘要
封面图片：同时提高钴基氧进化反应（OER）电催化剂的活性位点数量和内在活性是一个理想的目标。在编号为 CEY2432 的文章中，Yuan 等人报道了一种由金纳米粒子装饰的 ZIF-67 衍生的分层多孔硫化钴（称为 HP-Au@CoxSy@ZIF-67）杂化物。新颖的三维分层结构显著扩大了三相界面，加速了传质并暴露了活性中心。同时，金通过电荷转移调节了 Co 的电子结构，其中金和 NaBH4 还原剂产生了有趣的 "竞争效应"，调节了 Co2+/Co3+ 的相对比例。因此，HP-Au@CoxSy@ZIF-67 显示出优异的 OER 性能，可实现高效的水分离和锌空气电池应用。
Front cover image: Enhancing both the number of active sites available and the intrinsic activity of Co-based oxygen evolution reaction (OER) electrocatalysts simultaneously is a desirable goal. In the article number CEY2432, Yuan et al. reported a ZIF-67-derived hierarchical porous cobalt sulfide decorated by Au nanoparticles (denoted as HP-Au@CoxSy@ZIF-67) hybrid. The novel three-dimensional hierarchical structure significantly enlarges the three-phase interfaces, accelerating the mass transfer and exposing the active centers. Meanwhile, the electronic structure of Co is modulated by Au through charge transfer, wherein Au and NaBH4 reductant result in an interesting “competition effect” to regulate the relative ratio of Co2+/Co3+. Consequently, HP-Au@CoxSy@ZIF-67 displayed excellent OER performance, enabling efficient water splitting and Zn–air battery application.
