The selective electrochemical conversion of glycerol into value-added products is a green and sus-tainable strategy for the biomass utilization.In this work,Au nanowires(Au-NW)modified with polyethyleneimine(PEI)molecule(Au-NW@PEI)is obtained by an up-bottom post-modification approach.Physical characterization,molecular dynamics simulation and density functional theory demonstrate that the loose-packed PEI monolayer firmly and uniformly distribute on the Au-NW surface due to the strong Au-N interaction.Electrochemical experiments and product analysis display that PEI modification signif-icantly enhance the electro-activity of Au-NW for the glycerol electro-oxidation reaction(GEOR)due to the electronic effect.Meanwhile,the steric hindrance and electrostatic effect of PEI layer make the op-timizing adsorption of intermediates possible.Therefore,the selectivity of C3 product glyceric acid over Au-NW@PEI is increased by nearly 20％.The work thus indicates that the rational design of metal-organic interface can effectively elevate the electro-activity and selectivity of Au nanostructures,which may have wide application in biomass development.
