Abstract

The invention discloses a method for preparing a CaTi<2-x>M<x>O<4>(OH)<2> (M=Co, Ni, Fe) nanosheet by adopting a solvothermal method. The method comprises the following steps of dissolving a titanium compound into an organic solvent, stirring, filtering, washing and drying to obtain a TiO<2> precursor; dissolving the TiO<2> precursor and aqueous nitrate into an organic solvent to obtain a suspension liquid A; dissolving calcium chloride dihydrate into distilled water, and stirring uniformly to obtain a solution B; adding the solution B into the suspension liquid A dropwise, stirring and then dropwise adding a strong alkali solution to adjust the pH value of the solution B; and then putting the solution B into a reaction kettle to be reacted, and washing the product by distilled water to obtain the CaTi<2-x>M<x>O<4>(OH)<2> (M=Co, Ni, Fe) nanosheet. The process route is simple, and the cost is low; and the electrochemical performance of the CaTi<2-x>M<x>O<4>(OH)<2> is remarkably improved, so that the method has wide market prospect.

Description

technical field [0001] The invention relates to the technical field of capacitor electrochemistry, in particular to a method for preparing CaTi by solvothermal method. 2-x m x o 4 (OH) 2 (M = Co, Ni, Fe) nanosheet approach. Background technique [0002] The energy crisis is imminent, and the ecological environment is deteriorating day by day, which has caused serious harm to human existence. Energy shortage and serious environmental pollution are also one of the serious problems Jiangxi is facing. The utilization potential of renewable energy (including wind energy and solar energy) is great, which can fully meet the energy demand of sustainable development of human society. However, the development and utilization of renewable energy are seriously affected by natural conditions. Therefore, in order to solve the energy crisis and environmental pollution problems, a new type of high-efficiency energy storage device technology is developed. It is of great significance to...
