Abstract

For reductive upgrading of lignocellulosic biomass intermediates containing carbonyl groups, deoxygenation is critical to increase the energy density and storage lifetime of bio-oils. However, electrochemical that cleaves the C=O bond by hydrogenolysis to form an is extremely challenging because the C=O bond more readily undergoes to form an alcohol and the resulting alcohol C–O bond is more difficult to cleave by hydrogenolysis. In traditional organic , the uses Zn as a reductant to convert and to . Here we demonstrate the feasibility of the electrochemical , which uses Zn not as a stoichiometric reductant but as an electrocatalytic cathode in an electrochemical cell. The factors that affect the electrochemical hydrogenolysis and pathways on Zn and the mechanistic reasons why Zn is particularly good at hydrogenolysis are elucidated, revealing the advantages of electrochemical .
