Perovskite-Mixed oxides Interactions to Modulate Overall Water Splitting Performance of LaNiO3-CuxO/NiO Heterostructures

Abstract

A synergistic interface between LaNiO3 perovskite and Cu-Ni-O mixed oxide facilitates remarkable electrocatalytic activity by coupling Ni3+-mediated redox dynamics with oxygen-vacancy modulation. This deliberate integration of perovskite-mixed oxide heterostructures establishes a rational strategy to accelerate interfacial charge transfer, enabling overall water splitting at a low cell voltage of 1.5 V in alkaline conditions.
