Sumario:Spinel oxide NiCo(2)O(4) supported on a three-dimensional hierarchically porous graphene-like carbon (3D HPG) material has been firstly used to enhance the activity of Pt for glycerol electrooxidation. The addition of NiCo(2)O(4) into the Pt/HPG catalyst can significantly improve the catalytic performance for glycerol oxidation. When NiCo(2)O(4) is added to the Pt/HPG catalyst, the onset potential is 25 mV more negative than that on the Pt/HPG catalyst without NiCo(2)O(4). The current density at −0.3 V on the Pt–NiCo(2)O(4) (wt 10 : 1)/HPG electrode is 1.3 times higher than that on the Pt (30 wt%)/HPG electrode. The Pt–NiCo(2)O(4) electrode presented in this work shows great potential as an electrocatalyst for glycerol electrooxidation in an alkaline medium.
