Embodiment 1

[0017] At room temperature, dissolve 1mmol of zinc chloride, 2mmol of cobalt chloride and 12mmol of urea in 50ml of water and 30ml of ethanol, place on a magnetic stirrer, stir fully to dissolve them all. After stirring for 30 minutes, the solution was transferred to a 100ml stainless steel high-temperature and high-pressure reactor with a polytetrafluoroethylene liner, placed in a muffle furnace for hydrothermal reaction at 160°C for 18 hours, and then cooled to room temperature. The resulting product was washed with absolute ethanol Wash three times to remove possible residual impurities, centrifugally filter, and vacuum-dry at 60°C. The dried product was calcined at 500° C. for 2 h in an air atmosphere. Obtained mesoporous petal-like ZnCo 2 o 4 Nanosolid materials (such as figure 1 , figure 2 shown).

Embodiment 2

[0019] At room temperature, dissolve 1mmol of zinc chloride, 2mmol of cobalt chloride and 12mmol of urea in 50ml of water and 30ml of ethanol, place on a magnetic stirrer, stir fully to dissolve them all. After stirring for 30 minutes, the solution was transferred to a 100ml stainless steel high-temperature and high-pressure reactor with a polytetrafluoroethylene liner, placed in a muffle furnace for hydrothermal reaction at 120°C for 12 hours, then cooled to room temperature, and the resulting product was washed with absolute ethanol Wash three times to remove possible residual impurities, centrifugally filter, and vacuum-dry at 60°C. The dried product was calcined at 400° C. for 2 h in an air atmosphere. Get ZnCo 2 o 4 nano-solid materials.

Embodiment 3

[0021] At room temperature, dissolve 1mmol of zinc sulfate, 2mmol of cobalt sulfate and 15mmol of urea in 50ml of water and 30ml of ethanol, place on a magnetic stirrer, and stir fully to dissolve them all. After stirring for 30 minutes, transfer the solution to a 100ml stainless steel high-temperature and high-pressure reactor with a polytetrafluoroethylene liner, place it in a muffle furnace for hydrothermal reaction at 180°C for 24 hours, and then cool to room temperature. Wash three times to remove possible residual impurities, centrifugally filter, and vacuum-dry at 60°C. The dried product was calcined at 600° C. for 30 min in an air atmosphere. Get ZnCo 2 o 4 nano-solid materials.

Abstract

The invention relates to a synthetic method of a petal shaped ZnCo2O4 nanometer solid material with meso pores. At a room temperature, a certain amount of a zinc-containing compound, a cobalt-containing compound and a homogeneous precipitating agent urea are dissolved into a certain amount of a solvent, full stirring is carried out for a certain time, and a stable solution is formed. A hydrothermal reaction is carried out for the mixed solution, and the solution is cooled to a room temperature. Products are cleaned with deionized water or absolute ethyl alcohol and centrifugal filtering is carried out, and vacuum drying is carried out at 50-60 DEG C. Products are calcined at an air atmosphere, and the petal shaped ZnCo2O4 nanometer solid material with meso pores is prepared. The method has a simple preparation process and low material price, and enlarged production according to a proportion can be completed.
