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...

Abstract

The invention provides a kind of porous nano-flower Ni 2 The preparation method of P material includes the method of self-assembly induced by solvent volatilization to prepare nickel precursor, and then obtain nickel compound by roasting, and further use phosphorus source for phosphating treatment to obtain Ni 2 P material. Another aspect of the present invention provides a Ni 2 P material. Ni prepared by the present invention 2 The P material is used in the oxygen evolution reaction of electrolyzed water, and has fast catalytic kinetic performance and good catalytic stability. The invention has the advantages that the preparation method is simple to operate, the material has a stable morphology and structure, and has a porous structure, which is beneficial to the contact between the reactant and the catalyst during the catalytic reaction process, and the material transport of the reactant and the product.

Description

technical field [0001] The invention belongs to the technical field of porous materials and catalysis, in particular to a porous nano flower-like Ni 2 The preparation method of P material and the Ni prepared by using this method 2 P material. [0002] technical background [0003] Hydrogen is a clean energy. With the serious environmental pollution and the consumption of fossil energy, hydrogen is considered as an ideal new energy that can replace fossil energy. Hydrogen production by electrolysis of water is the simplest and most feasible method of hydrogen production. In order to save cost and accelerate the reaction, the efficiency of water electrolysis is often improved by designing efficient catalysts. The electrolysis of water includes the hydrogen evolution reaction on the cathode and the oxygen evolution reaction on the anode. At present, the best catalysts for hydrogen evolution are still platinum and platinum-based catalysts, and the best oxygen evolution catalys...
