▎ 摘　　要

NOVELTY - A zinc sulfide nanowire/copper sulfide nanoparticles/reduced graphene oxide composite material is formed by depositing copper sulfide nanoparticles on the surface of zinc sulfide nanowires to form a line-point nanocomposite structure, and depositing the nanocomposite structure on the surface of two-dimensional reduced graphene oxide. The zinc sulfide nanowires have diameter of 8-18 nm, and length of 100-200 nm. The copper sulfide nanoparticles have diameter of 4-8 nm. USE - Zinc sulfide nanowire/copper sulfide nanoparticles/reduced graphene oxide composite material used for supercapacitors and photocatalysis applications (all claimed). ADVANTAGE - The zinc sulfide nanowire/copper sulfide nanoparticles/reduced graphene oxide composite material has excellent electrical properties and photocatalytic properties, and effectively avoids the volume change of zinc sulfide nanowire/copper sulfide nanoparticles during charging and discharging, and promotes excellent ion diffusion by having large electrode/electrolyte interface. The zinc sulfide nanowire/copper sulfide nanoparticles prevent graphene aggregation and increase the surface area of composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of zinc sulfide nanowire/copper sulfide nanoparticles/reduced graphene oxide composite material, which involves dispersing 1.6-2 mmol zinc nitrate, and 1.6-2 mmol copper nitrate in 10 ml deionized water to obtain solution (A), dispersing 6-6.2 mmol thiourea in 10 ml ethylenediamine to obtain solution (B), dispersing 0.01-0.015 g graphene oxide in a mixed solution of 10 ml deionized water and 10 ml absolute ethanol to obtain solution (C), dispersing solution (A)-(C) for 1 hour, dripping solution (A) to solution (C) within 30 minutes, stirring for 30 minutes, and dripping solution (B) to solution (C) within 30 minutes, stirring for 30 minutes, transferring it to 50 ml reaction kettle, and reacting at 180 degrees C for 12 hours and washing the obtained product with deionized water and absolute ethanol and drying.
