Abstract

The invention relates to a pyrolytic carbon / molybdenum disulfide nanosheet / graphene composite material patterned micro-electrode and a micro-processing technology thereof. The pyrolytic carbon / molybdenum disulfide nanosheet / graphene composite material patterned micro-electrode comprises the steps of 1) mixing graphene, sodium molybdate dihydrate, thiourea and water uniformly according to a mass ratio of 1-10:400:600-700:1000-30000, then putting the mixture in a reaction kettle for hydro-thermal synthesis reaction, centrifuging the mixture after subjected to the hydro-thermal synthesis reaction, drying to obtain a solid product, and grinding the solid product to obtain a molybdenum disulfide nanosheet / graphene material; and 2) mixing photo-resist with the molybdenum disulfide nanosheet / graphene uniformly, then coating the mixture on a substrate for drying, then performing ultra-violet lithography, development and washing for the substrate, and finally performing high-temperature pyrolytic reaction to obtain the pyrolytic carbon / molybdenum disulfide nanosheet / graphene composite material patterned micro-electrode. The obtained micro-electrode has good electrochemical performance and has good application foreground in the fields such as micro-sensors and tiny energy storage devices.
