Embodiment 1
[0036] The materials and reagents used in the following examples can be obtained from commercial sources unless otherwise specified.
[0037] The porous nano flower-shaped Ni of the present embodiment 2 The preparation method of P material adopts the preparation method of nickel-containing compound precursor, including the following steps:
[0038] (1) Synthesis of nickel-containing compounds: Add 1.45g of triblock copolymer P123 (molecular weight=5800) into a mixed solution containing 1.53mL of concentrated nitric acid and 13mL of n-butanol, and dissolve completely in a constant temperature water bath at 40°C. Add 0.01mol nickel nitrate (Ni(NO 3 ) 2 ·6H 2 O), magnetically stirred for 10-30min to make it completely dissolved, then transferred the mixed solution to a 120°C oven and heated for 3.5h, cooled to room temperature, washed 3-4 times with ethanol, centrifuged to obtain the product, and placed in 40°C After drying overnight in a vacuum oven, the resulting material w...
