Abstract

A hydroxide/graphene hybrid electrocatalyst for oxygen evolution reaction is proposed by Q. Zhang and co-workers, as described on page 4516. Nanosized hydroxide active centers are uniformly and strongly hybridized into a nitrogen-doped graphene framework via defect-anchored nucleation and spatially confined growth. The as-obtained hydroxide/graphene is demonstrated to overperform commercial Ir/C catalysts and compete favorably against reported alternatives for high-performance oxygen evolution reactivity.

Keywords: catalysts; graphene; layered double hydroxides; oxygen evolution; transition metal hydroxides.
