Defect engineering and interface are two efficient approaches to promote the electrocatalytic performance of transition metal oxides (TMOs) by modulating local electronic structure inducing a synergistic effect but usually require costly complicated processes. Herein, facile electrochemical etching method is proposed for controllable tailoring defects in three-dimensional (3D) open nanonetcage CoZnRuOx heterostructure via situ remove partial ZnO. The highly 3D nanostructures, numerous defects, multicomponent heterointerfaces endow nanonetcages with more accessible active sites, moderated structure, strong effect, thereby enabling them not only deliver an ultralow overpotential (244 mV @ 10 mA cm-2) oxygen evolution reaction (OER) also high-performance overall water electrolysis coupling commercial Pt/C, potential 1.52 V at cm-2. Moreover, experiments characterizations reveal that remaining Zn2+ can facilitate OH- adsorption charge transfer, which further improves OER performance. This work proposes promising strategy creating surface heterostructured TMOs provides insights understand defect- interface-induced enhancement electrocatalysis.

Abstract Ru‐based materials hold great promise for substituting Pt as potential electrocatalysts toward water electrolysis. Significant progress is made in the fabrication of advanced electrocatalysts, but an in‐depth understanding engineering methods and induced effects still their early stage. Herein, we organize a review that focusing on strategies substantial improvement electrocatalytic OER HER performance catalysts, including geometric structure, interface, phase, electronic size, multicomponent engineering. Subsequently, enhancement catalytic by these are also elucidated. Furthermore, some representative applications well presented. Finally, challenges prospects elaborated future synthesis more effective catalysts boost application.
