Pd doped three-dimensional porous Ni film supported on Ni foam and its high performance toward NaBH4 electrooxidation

A novel, simple 3D electrode with high performance for NaBH4 oxidation is prepared. The oxidation current density on the Pd-porous Ni/Ni foam electrode at a potential of −0.6 V (2.2 A mg−1) is about 22 times of that for Pd/C (0.1 A mg−1) reported previously.
