We have developed the CoMoO4 nanorods (NRs) electrode with a specific one-dimensional nanostructure, which exhibited superior electrocatalytic performance for Oxygen Evolution Reaction (OER), such as lower potential (343 mV at a current density of 10 mA cm(-2)), Tafel slope (67 mV decade(-1)) and excellent catalytic stability (for 10 h). Benefiting from enhancement of electrical conductivity and one-dimensional nanostructure, the CoMoO4 NRs show improved OER activity than Co3O4 cubes, demonstrating that one-dimensional nanostructures could be promising to achieve the OER catalysts with excellent property.
