Abstract

The invention relates to a micron-size nickel phosphide material, as well as a preparation method and application of the micron-size nickel phosphide material. The micron-size nickel phosphide material takes the shape of a hollow sea urchin, and the nickel phosphide is a compound of Ni2P and Ni12P5. The preparation method comprises the steps of synthesizing a ball-shaped Ni simple substance and synthesizing the nickel phosphide. The nickel phosphide synthesized through the method is a sea-urchin-shaped hollow superstructure material, has a very large specific surface area and has a better catalyzing effect on reduction in catalyzing p-nitrophenol, the preparation condition is mild, and the reaction is simple.

Description

technical field [0001] The invention belongs to the technical field of preparation of micro-nano materials, and in particular relates to a micron-level nickel phosphide material and its preparation method and application. Background technique [0002] p-Aminophenol is an important organic intermediate widely used in medicine, dyes and organic synthesis. In the pharmaceutical industry, p-aminophenol is mainly used in the synthesis of medicines such as acetaminophen, buprofen, and vitamin B 1 , compound nicotinamide, etc.; 4010NA, 4020, 4030 and other p-phenylenediamine antioxidants can be synthesized in the rubber industry; in the dye industry, it is an intermediate for the production of disperse dyes, acid dyes, direct dyes, sulfur dyes and fur dyes. Can produce sulfur red brown B 3 R, sulfur sapphire blue CV, sulfur reduction black CLG, sulfur new blue FBL, fur brown, etc.; p-aminophenol can also be used to produce photographic developer Metol, and can also be directly us...
