Abstract
Nanoarrays In article number 2303073, Yan Zhao, Limin Qi, and co-workers construct unique Mo-doped ruthenium–cobalt oxide (Mo–RuCoOx) nanosheet arrays as a bifunctional electrocatalyst for efficient HER and OER, achieving outstanding performance toward alkaline overall water splitting. The combination of electronic and vacancy engineering through Mo-doping coupled with oxygen vacancy generation endows the Mo–RuCoOx nanoarrays with optimized electronic structure, desired adsorption energy of intermediates, and remarkably enhanced activity.
