Popis:	Developing efficient renewable electrocatalytic processes for chemical manufacture is of commercial interest, especially from the biomass-derived feedstock. Selective electrocatalytic hydrogenation (ECH) of biomass-derived lignin monomers to high-value oxygen-functional compounds is promising to achieve this goal. However, ECH has to date lacked the satisfactory selectivity to upgrade lignin monomers to high-value oxygenated chemicals due to the reduction of vulnerable -OCH3 that exists in most lignin monomers. Herein we report carbon-felt supported ternary RhPtRu catalysts with a record faradaic efficiency (FE) of 62.8% and a selectivity of 91.2% to the methoxy-cyclohexanes (2-methoxy-cyclohexanol and 2-methoxy-cyclohexanone) from guaiacol, via a strong inhibition effect on the cleavage of methoxy group, representing the best performances compared to previous reports. We further conducted a brief TEA to demonstrate a profitable ECH of guaiacol to high-value methoxy-cyclohexanes using our designed RhPtRu ternary catalysts.
