Embodiment 1
[0040] A preparation method of molybdenum selenide nanosheet array / Mo foil composite material, comprising the following steps:
[0041] A, take by weighing 2mmol selenium powder and join in 10ml hydrazine hydrate, stir until dissolving, obtain selenium powder hydrazine hydrate solution; Measure 30mL deionized water and 60mL ethanol, stir and mix; Add this deionized water and ethanol mixed solution to obtain In the obtained selenium powder hydrazine hydrate solution, stir and mix evenly to obtain a mixed solution;
[0042] B. Transfer the mixed solution obtained in step A to a polytetrafluoroethylene-lined reaction kettle, put in a Mo foil with a size of 4cm×4cm, close the reaction kettle and put it in a constant temperature box, and heat it at a constant temperature at 220°C. 10h;
[0043] C. After the reaction, cool down to room temperature naturally, take out the Mo foil from the reaction kettle, wash it with deionized water and ethanol for 5 times, and then put it in a vac...
