Amorphous MoS x developed on Co(OH) 2 nanosheets generating efficient oxygen evolution catalysts

aMoS x /Co(OH) 2 nanosheets were synthesized by forming amorphous MoS x on Co(OH) 2 nanosheets. The aMoS x /Co(OH) 2 nanosheets demonstrate excellent OER catalytic activity with only 350 mV at 10 mA cm −2 . The incorporation of amorphous molybdenum sulfide enhances the hydrophilicity, favoring the availability of reactant, and induces electron transfer for enhancing the OER catalytic activity of Co(OH) 2 .
