【摘要】:Three-dimensional(3D) graphene composites have drawn increasing attention in energy storage/conversion applications due to their unique structures and properties.Herein,we synthesized 3D honeycomb-like Ni_3S_2@graphene oxide composite(3D honeycomb-like Ni_3S_2@GO) by a one-pot hydrothermal method.We found that positive charges of Ni~(2+) and negative charges of NO_3~- in Ni(NO_3)_2 induced a transformation of graphene oxide with smooth surface into graphene oxide with wrinkled surface(w-GO).The w-GO in the mixing solution of Ni(NO3)2/thioacetamide/H2 O.evolved into 3D honeycomb-like Ni_3S_2@GO in solvothermal process.The GO effectively inhibited the aggregation of Ni_3S_2 nanoparticles.Photoelectrochemical cells based on 3D Ni_3S_2@GO synthesized at 60 m Ml-1 Ni(NO3)2 exhibited the best energy conversion efficiency.3D Ni_3S_2@GO had smaller charge transfer resistance and larger exchange current density than pure Ni_3S_2 for iodine reduction reaction.The cyclic stability of 3D honeycomb-like Ni_3S_2@GO was good in the iodine electrolyte.Results are of great interest for fundamental research and practical applications of 3D GO and its composites in solar water-splitting,artificial photoelectrochemical cells,electrocatalysts and Li-S or Na-S batteries.
