Amorphous MoSx 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.
