Direct Growth of MoS₂ Microspheres on Ni Foam as a Hybrid Nanocomposite Efficient for Oxygen Evolution Reaction

MoS2 microspheres are directly grown on the conductive Ni foam and the as-obtained MoS2 -Ni electrodes exhibit highly efficient electrocatalytic performances for oxygen evolution in 1.0 m NaOH, displaying a rather low overpotential of 0.310 V at 20.0 mA cm(-2) , a high current density, good cyclic stability, and excellent flexibility.
