Method for preparing Ti3C2-coated Co-MOF super capacitor material in hydrothermal mode

The invention relates to a hydrothermal preparation method and an application of the hydrothermal preparation method in the aspect of super capacitor performance. The preparation method comprises thefollowing steps: in a fuming cupboard, taking hydrofluoric acid and Ti3AlC2 into a container, etching, washing and drying to obtain a Ti3C2 material; taking cobalt chloride hexahydrate and terephthalic acid and dissolving in a mixed solution composed of Ti3C2, N, N-dimethylformamide dispersion liquid, water and ethyl alcohol, and obtaining a mixed solution; transferring into a hydrothermal reaction kettle with a polytetrafluoroethylene lining, centrifugally collecting precipitates from a sample obtained by hydrothermal treatment, respectively centrifugally washing with ethanol and water, and drying to obtain the Ti3C2-coated Co-MOF nano material with two-dimensional morphology. The preparation method has the characteristics of low preparation cost, large specific capacity and good conductivity, so that the materia
