Grain‐Boundary‐Rich RuO 2 Porous Nanosheet for Efficient and Stable Acidic Water Oxidation
Indexed incrossrefpubmed
Abstract
Abstract RuO 2 has been considered as the most likely acidic oxygen evolution reaction (OER) catalyst to replace IrO 2 , but its performance, especially long‐term stability under harsh acidic conditions, is still unacceptable. Here, we propose a grain boundary (GB) engineering strategy by fabricating the ultrathin porous RuO 2 nanosheet with abundant of grain boundaries (GB‐RuO 2 ) as an efficient acid OER catalyst. The involvement of GB induces significant tensile stress and creates an unsaturated coordination environment, effectively optimizing the adsorption of intermediates and stabilizing active site structure during OER process. Notably, the GB‐RuO 2 not only exhibits a low overpotential (η 10 =187 mV)…
