Combining Co₃S₄ and Ni:Co₃S₄ nanowires as efficient catalysts for overall water splitting: an experimental and theoretical study
Published 2021“…Following a sulfuration process, Co₃O₄ nanowires are entirely converted into Co₃S₄ nanowires showing greatly improved OER catalytic performances with an overpotential of 283 mV (instead of 371 mV for Co₃O₄) to deliver a current density of 10 mA cm⁻². Besides, when doping the surface of these Co₃S₄ nanowires with small amounts of nickel, the resulting Ni:Co₃S₄ nanowires exhibit an HER overpotential of 199 mV to reach 10 mA cm⁻². …”
