Happy Co Lucky Local The cover picture shows water electrolysis at carbonaceous nanoparticle aggregates as a catalyst for the hydrogen‐evolution reaction. In their Communication on p. 2197 ff., J. Maruyama et al. describe tuning of the local structure surrounding Co atoms contained in the catalyst, as the center of the active site, which was described by the Co‐K edge X‐ray absorption near‐edge structure. The tuned structure and limited decomposition of the active site led to the enhancement of the catalytic activity and the high efficiency in the proton‐exchange membrane type water electrolyzer, which is a promising energy conversion system suitable to intermittent and fluctuating renewable energy sources.
