Frontispiece: Self-optimizing Cobalt Tungsten Oxide Electrocatalysts toward Enhanced Oxygen Evolution in Alkaline Media

A modular design strategy for self-optimizing electrocatalyst is reported by Dandan Gao et al. in their Research Article (e202424074), featuring nanostructured Co-W oxide on Cu oxide microflower supports. The catalyst exhibits in situ enhanced oxygen evolution performance, attributed to increased electrochemical surface area, lower charge transfer resistance, and adaptation of active sites from W centers to Co centers. This work presents a promising approach for designing self-optimizing electrocatalysts for complex multielectron reactions.
