However, the commercialization of this technology is hindered by the sluggish kinetics and high overpotential of the oxygen evolution reaction (OER) at the anode, leading to elevated energy consumption. Replacing OER with the methanol oxidation reaction (MOR) offers a more energy-efficient alternative, yet the development of electrocatalysts that deliver high activity, selectivity, and long-term stability at ampere-level current densities remains a notable challenge. Here, we report an interface-engineered RuO\n                    <jats:italic toggle=\"yes\">\n                      <jats:sub>x<\/jats:sub>\n                    <\/jats:italic>\n                    @Mo(Mn)O\n                    <jats:italic toggle=\"yes\">\n                      <jats:sub>x<\/jats:sub>\n                    <\/jats:italic>\n                    [RuO\n                    <jats:sub>x<\/jats:sub>\n                    nanoparticles deposited on a Mo(Mn)O\n                    <jats:sub>x<\/jats:sub>\n                    matrix] catalyst featuring Ru\u2500O sites with an asymmetric coordination environment, which enables optimized electron transfer and stabilization of highly active Ru species.
