Abstract
Abstract The development of active, acid-stable and low-cost electrocatalysts for oxygen evolution reaction is urgent and challenging. Herein we report an Iridium-free and low ruthenium-content oxide material (Cr 0.6 Ru 0.4 O 2 ) derived from metal-organic framework with remarkable oxygen evolution reaction performance in acidic condition. It shows a record low overpotential of 178 mV at 10 mA cm −2 and maintains the excellent performance throughout the 10 h chronopotentiometry test at a constant current of 10 mA cm −2 in 0.5 M H 2 SO 4 solution. Density functional theory calculations further revealed the intrinsic mechanism for the exceptional oxygen evolution reaction performance, highlighting the influence…
