Abstract

The invention discloses a preparation method of an MXene/NiCoP/NF composite material. The preparation method comprises the following steps: firstly, preparing a solution with the same etching effect as hydrofluoric acid from a certain amount of lithium fluoride and hydrochloric acid, and then slowly putting Ti3AlC2 into the solution for etching to obtain an MXene material; and dissolving the prepared MXene material, nickel salt and cobalt salt into deionized water and ethanol in a certain proportion, stirring for a certain time, putting the obtained mixed solution and foamed nickel into a reaction kettle, carrying out hydrothermal reaction, drying, putting the obtained material, putting the dried material and sodium hypophosphite monohydrate into a tubular furnace, and annealing in argon to obtain the MXene/NiCoP/NF composite material. According to the invention, the preparation process is simple, the cost is low, the safety is high, the prepared material has excellent electrochemical performance, and the defects of complex process, high cost and poor electrochemical performance of the electrode material in the prior art are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a preparation method of MXene / NiCoP / NF composite material. Background technique [0002] Energy is used in all aspects of human survival and development, but it is like a double-edged sword. While benefiting human life, it also has a negative impact on human production and life. Fossil fuels (petroleum, coal, and natural gas, etc.) are the main energy sources in the current society, but they contain a large amount of impurities such as nitrogen, phosphorus, and sulfur, and a large amount of harmful gases (SO 2 , SO 3 , NO, NO 2 ), causing adverse impacts on the environment and destroying the ecosystem. At the same time, fossil fuel is a non-renewable resource, and excessive and unreasonable exploitation and use will always cause energy depletion. Therefore, it is of great practical significance to find a clean energy source that is non-polluting, renewab...
