Embodiment approach 1

[0009] Take a piece of nickel foam of 5×2 square centimeters, disperse 5g of red phosphorus powder on the upper surface of the nickel foam, then place it in a quartz boat, put it into a tube furnace, and feed argon gas at a flow rate of 20mL / min, then Directly raise the temperature to 700°C, react at this temperature for 30 minutes, and then lower it to room temperature under the protection of argon. The product is soaked in 6mol / L hydrochloric acid in a water bath at 80°C for 5 hours, then washed to neutrality, and dried in vacuum at 60°C for 3 hours. A three-dimensional macroporous nickel phosphide is obtained.

Embodiment approach 2

[0011] The reaction temperature in Embodiment 1 is changed from 700°C to 750°C, and other conditions remain unchanged, to obtain three-dimensional macroporous nickel phosphide.

Embodiment approach 3

[0013] The reaction time in embodiment 1 is changed from 30min to 60min, and other conditions are unchanged, and three-dimensional macroporous nickel phosphide is obtained.

The method has the advantages of simplicity in operation, good process repeatability, stable product quality, and suitability for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of inorganic material preparation technology, and relates to a preparation method of inorganic materials, in particular to a synthesis method of a three-dimensional macroporous metal phosphide. It can be applied to battery materials, superconducting materials and catalytic materials, etc. Background technique [0002] The three-dimensional macroporous structure possesses optimized chemical and physical properties due to its hollow feature, thus holding promising application prospects. Due to the smaller material density, larger specific surface area, and loadable space, three-dimensional macroporous particles can be used as assembly units for lightweight materials and catalysts with high surface activity. Metal phosphides have attracted the attention of scholars due to their excellent physical and chemical properties such as superconductivity, ferromagnetism, and catalytic activity. However, the controlled ...
