N-doped mixed Co, Ni-oxides with petal structure as effective catalysts for hydrogen and oxygen evolution by water splitting.

ABSTRACT: Developing electrocatalytic nanomaterials for green H₂ energy is inseparable from the exploration of novel materials and internal mechanisms for catalytic enhancement. In this work, nano-petal N-doped bi-metal (Ni, Co) and bi-valence (+2, +3) (Ni_1-x Co _x )²⁺Co₂ ³⁺O₄ compounds have been in situ grown on the surface of Ni foam. The N^3- atoms originate from the amino group in urea and doped in the compound during annealing. The as-synthesized N-doped (Ni_1-x Co _x )²⁺Co₂ ³⁺O₄ nano-petals demonstrate commendable hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) bi-functional catalytic effic
