摘要

•Series of cation-doped Co3O4 nanoarrays with same morphology are synthesized.•Experiments and DFT simulations reveal the valence regulation of Co cation.•CCO catalyst exhibits the lowest OER overpotential as lower valence state of Cu.•Controllable morphology benefits to theoretically study of the real catalysts.
