A high crystalline NiCo2O4 supported on carbon black has been directly synthesized on carbon black via a simple, one step intermittence microwave heating method. Carbon black which is induced into NiCo2O4 will reduce overpotential and remarkably improve current for oxygen evolution reaction in alkaline medium. The activity of NiCo2O4/C is much higher than that of NiO/C and Co3O4/C for oxygen evolution reaction. The activity of NiCo2O4/C will be further improved by NiO. The NiO-NiCo2O4 (3:1 by molar ratio)/C shows the highest activity. (C) 2014 Elsevier B.V. All rights reserved.
