Abstract

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.
