Carbon-supported molybdenum sulfide nanosheet and nickel sulfide nanocrystalline composite material, preparation and application
The invention belongs to the technical field of functional nano composite material preparation, and particularly relates to a carbon-loaded molybdenum sulfide nanosheet and nickel sulfide nanocrystalline composite material, preparation and application. The preparation method of the composite material comprises the following steps: (1) mixing nickel salt with a complexing agent, and preparing a carbon frame composite material by adopting a hard template method; (2) mixing the carbon framework composite material, ammonium heptamolybdate and thiourea, and performing hydrothermal reaction to prepare a carbon-loaded MoSx nanosheet composite material; (3) under the action of a vulcanizing agent, roasting the carbon-loaded MoSx nanosheet composite material, so as to prepare a carbon-loaded MoS2 nanosheet and NiS2 nanocrystalline composite material; wherein the roasting temperature ranges from 300 DEG C to 350 DEG C. The composite material prepared by the invention is applied to a sodium ion battery or a sodium ion capacitor, and can show high specific capacity, good rate capability and cycle performance..
