Abstract
Abstract RuO 2 is one of the benchmark electrocatalysts used as the anode material in proton exchange membrane water electrolyser. However, its long‐term stability is compromised due to the participation of lattice oxygen and metal dissolution during oxygen evolution reaction (OER). In this work, weakened covalency of Ru−O bond was tailored by introducing tensile strain to RuO 6 octahedrons in a binary Ru−Sn oxide matrix, prohibiting the participation of lattice oxygen and the dissolution of Ru, thereby significantly improving the long‐term stability. Moreover, the tensile strain also optimized the adsorption energy of intermediates and boosted the OER activity. Remarkably, the RuSnO x electrocatalyst…
