    “…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. …”
