Abstract

The invention belongs to the field of functionalized porous nanometer materials, and relates to a preparation method of a ferrocobalt sulfide nanotube loaded carbon sponge flexible composite material.The preparation method comprises the following specific steps: cutting commercial tripolycyanamide sponge, then washing with distilled water and absolute ethyl alcohol, after drying, in a nitrogen orargon atmosphere, burning the tripolycyanamide sponge through temperature programming, carrying out carbonization treatment, and cooling to obtain carbon sponge; preparing a mixed solution containinga ferric salt and a cobalt salt, immerging the carbon sponge into the mixed solution, adding a pH accessory ingredient, carrying out a hydrothermal reaction to obtain a ferrocobalt precursor-carbon sponge composite material, then immerging the ferrocobalt precursor-carbon sponge composite material into a vulcanizing agent solution, and carrying out a secondary hydrothermal reaction to obtain theferrocobalt sulfide nanotube loaded carbon sponge flexible composite material. According to the preparation method, the flexible, porous and self-supporting carbon sponge is taken as a growth template, and the difficulty that a nanometer material is easy to cluster is solved successfully; and the obtained composite material has a great number of exposed active sites, abundant holes and good conductivity.

Description

technical field [0001] The invention belongs to the field of functionalized porous nanometer materials, and in particular relates to a preparation method of a carbon sponge flexible composite material supported by cobalt-iron sulfide nanotubes. Background technique [0002] In recent years, with the depletion of non-renewable energy sources, people's demand for new energy sources has increased dramatically. Clean energy such as solar energy, wind energy, and tidal energy has the disadvantages of intermittent and discontinuous, so it is urgent to develop efficient and economical new energy storage and conversion technologies. Supercapacitors, fuel cells, and lithium-ion batteries are considered to be the three most promising electrochemical energy storage and conversion systems. In order to enhance the energy storage efficiency and manufacturing cost of the above three energy storage and conversion systems, thereby promoting the industrialization of this new energy technolog...
