Abstract

Hybrid bilayer membrane (HBM) system consists of a monolayer of lipid molecules coated on self-assembled monolayer (SAM) that is attached onto an electrode surface.1 Many studies have indicated that the HBM system could influence the product selectivity of oxygen reduction reaction (ORR) by controlling the rate of electron and proton transfer.2-6 Similar to ORR, selective glycerol oxidation is challenging because multiple proton and electron transfer steps and parallel reaction pathways are involved. In this paper, we demonstrated that selective electrocatalytic glycerol oxidation can be performed on Ni-cyclam functionalized ITO electrode surface in a HBM system. Our results show that the system could regulate the thermodynamics of glycerol oxidation reaction to undergo a two-proton two-electron pathway for selective oxidization of glycerol into glyceraldehyde as the major value-added product.
