摘要	Single-atom catalysts have been widely investigated for several electrocatalytic reactions except electrochemical alcohol oxidation. Herein, we synthesize atomically dispersed platinum on ruthenium oxide (Pt/RuO) using a simple impregnation-adsorption method. We find that Pt/RuO has good electrocatalytic activity towards methanol oxidation in an alkaline media with a mass activity that is 15.3-times higher than that of commercial Pt/C (6766 vs. 441 mA mg). In contrast, single atom Pt on carbon black is inert. Further, the mass activity of Pt/RuO is superior to that of most Pt-based catalysts previously developed. Moreover, Pt/RuO has a high tolerance towards CO poisoning, resulting in excellent catalytic stability. Ab initio simulations and experiments reveal that the presence of Pt‒O (3-fold coordinatively bonded O)‒Ru (coordinatively unsaturated Ru) bonds with the undercoordinated bridging O in Pt/RuO favors the electrochemical dehydrogenation of methanol with lower energy barriers and onset potential than those encountered for Pt‒C and Pt‒Ru.
