- Abstract
- Replacingthe oxidation of water with the electrocatalytic oxidationof methanol is an attractive route to level the cost of H-2 production with value-added chemicals; however, this reaction hasbeen notoriously known for quickly poisoning electrocatalysts and/orsliding into complete oxidation, thereby producing CO2.Here, we report an acid-stable Ru metal atom array that is supportedby MnO2 nanofibers (Ru-MAC/MnO2) for the electrocatalyticvalorization of methanol to methyl formate (MF). The productivityof MF is 10 to 100 times higher than those reported in thermal- andphotocatalytic processes at commercially viable current densities.Our experimental and simulation results demonstrate that the atomarray possesses long-term electrochemical stability and prefers theMF pathway without generating *CO intermediates. The synergistic intersitemetal-metal and metal-support electronic interactionsendow Ru-MAC/MnO2 with outstanding structural stabilitytoward large-current-density methanol electrolysis.
