Abstract

The invention relates to a molybdenum sulfide / nickel oxide composite material and a preparation method and application thereof. The structure of the composite material is that a nickel oxide nanosheet grows on a molybdenum sulfide nanosheet. The preparation method comprises the steps of dispersing the molybdenum sulfide nanosheet into a polar solvent and carrying out ultrasonic treatment to obtain a molybdenum sulfide nanosheet dispersion liquid; dissolving a nickel salt into the molybdenum sulfide nanosheet dispersion liquid, carrying out ultrasonic treatment to obtain a mixed liquid, adding a complexing agent, reacting at 80-100 DEG C for 6-24 hours and washing and drying the product to obtain a molybdenum sulfide / nickel hydroxide composite material; and carrying out thermal treatment to obtain the molybdenum sulfide / nickel oxide composite material. The preparation process is simple and easy to operate, the reaction temperature is low, the security coefficient is high, and the prepared molybdenum sulfide / nickel oxide composite material can be used as an excellent electrode material for new energy devices of a high-performance super-capacitor, a lithium battery and the like.

Description

technical field

[0001] The invention belongs to the field of nickel oxide composite material and its preparation, in particular to a molybdenum sulfide / nickel oxide composite material and its preparation method and application. Background technique

[0002] As a class of transition metal oxides, nickel oxide has the advantages of non-toxicity, environmental friendliness, easy preparation, good catalytic performance, and high theoretical specific capacity. Nickel oxide is considered to be an ideal supercapacitor material to replace ruthenium oxide (currently commercial supercapacitor electrode material) because of its wide source, easy preparation, and low price, and a lot of research has been done on it. At present, the preparation methods of nickel oxide electrode materials mainly include sol-gel method, electrochemical deposition method, chemical precipitation method, thermal decomposition method, template method, hydrothermal method and so on. The morphology of nickel ox...
