    “…In situ scanning electrochemical microscopy study validates the HOR activity resulting from the Ru-Ni diatomic sites. Furthermore, in situ x-ray absorption spectroscopy and computational studies unveil a synergistic interaction between Ru and Ni to promote the molecular H(2) dissociation and strengthen OH adsorption at the diatomic sites, and thus enhance the kinetics of HOR.…”
