▎ 摘　　要

Spinel oxide NiCo2O4 firstly has been explored to promote activity of Au for glycerol electrooxidation, which is supported on a three-dimensional hierarchical porous graphene-like carbon (3D HPG) material. Addition NiCo2O4 into the Au/HPG catalyst can significantly improve the catalytic performance for glycerol oxidation. When NiCo2O4 is added to the Au/HPG, onset potential is more 108 mV negatively than that on the Au/HPG. Peak current density on the Au/NiCo2O4(wt 6:1)/HPG is 5.1 times as high as that on the Au(20wt%)/HPG. The Au/NiCo2O4 in this work shows a great potential as electrocatalyst for glycerol electrooxidation in alkaline medium.
