Preparation method of MoO2 and Mn2P2O7 mixed material

The invention provides a preparation method of a MoO2 and Mn2P2O7 mixed material. The preparation method comprises the following steps: S1, putting a molybdenum source and a manganese source into ionic liquid, and heating at a set temperature for a certain time to synthesize a precursor; and S2, mixing the precursor with sodium hydrogen hypophosphite, and calcining at a set temperature for a certain time to obtain the MoO2 and Mn2P2O7 mixed material. According to the preparation method, 1-butyl-3-methylimidazole bis (trifluoromethane) sulfimide is used as a reaction solvent for preparing a MoO2 and Mn2P2O7 mixed material, 1-butyl-3-methylimidazole bis (trifluoromethane) sulfimide is used as an ionic liquid, and due to the low volatility of 1-butyl-3-methylimidazole bis (trifluoromethane) sulfimide, the MoO2 and Mn2P2O7 mixed material can be obtained; the problem of poor safety caused by high pressure of a closed container due to continuous volatilization of water in a hydrothermal method can be solved, so tha
