Description
Summary:Carbon black is used as conducting support for NiO nanoparticles, and noble metal particles are well dispersed on NiO/C with an average diameter of 4–8 nm. Benefiting synergistic effect, NiO/C by adding noble metal exhibits superior electrochemical activity and excellent stability for oxygen evolution reaction in water splitting. A catalyst with a weight ratio of Au to NiO of 1:2 gives the best performance. Onset potential on the Au-NiO(wt 1:2)/C electrode shifts more negatively than that on Pt-NiO(wt 1:2)/C and Pd-NiO(wt 1:2)/C, and onset potential on the Au-NiO(wt 1:2)/C electrode is lower than that on the other electrodes.
