The porous Fe-doped NiMoO4 nanotube were fabricated hierarchically through room-temperature Fe atoms incorporation and subsequent thermal treatment under air atmosphere.The Fe-doped NiMoO4 nanotube exhibited much better electrocatalytic activity for the oxygen evolution reaction(OER) than single-phase.Typically,the Ni0.75Fe0.25MoO4 shown performance favorably comparable to the state of the NiMoO4 OER catalysts recently reported.To drive a current density of 10mA/cm2,the Ni0.75Fe0.25MoO4 catalyst only required an overpotential of 253mV,and the tafel slope of Ni0.75Fe0.25MoO4 was only 41mV/dec,which was comparable to the integrated performance of commercial IrO2.Furthermore,the Ni0.75Fe0.25MoO4 catalyst showed a stable performance operated at the long-term test.The superior activity and long-term stability demonstrated that the hierarchical Ni0.75Fe0.25MoO4 nanotube catalyst had promising potential for application in large-scale water splitting.
