ABSTRACT
Spinel oxide NiCo2O4 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 NiCo2O4 into the Pt/HPG catalyst can significantly improve the catalytic performance for glycerol oxidation. When NiCo2O4 is added to the Pt/HPG catalyst, the onset potential is 25 mV more negative than that on the Pt/HPG catalyst without NiCo2O4. The current density at -0.3 V on the Pt-NiCo2O4 (wt 10 1)/HPG electrode is 1.3 times higher than that on the Pt (30 wt%)/HPG electrode. The Pt-NiCo2O4 electrode presented in this work shows great potential as an electrocatalyst for glycerol electrooxidation in an alkaline medium.
