The present invention uses a phosphorus source as a reactant, an ammonium salt as a catalyst, mixes the phosphorus source and the ammonium salt under low oxygen conditions, heats the reaction, and obtains the purple phosphorus-based material after cooling. By using the ammonium salt as a catalyst, the conversion of the phosphorus source to the purple phosphorus-based material is promoted under oxygen-free and high temperature conditions, and the generation of harmful byproducts is reduced. At the same time, the ammonium salt is used as a catalyst, which is easily decomposed into gas in the reaction, and will not be sintered and deactivated at high temperature, thereby reducing production costs, improving resource utilization efficiency, and being easy to separate from the product, improving the quality of the product, realizing efficient and low-cost industrial production of purple phosphorus-based materials, and then promoting the wide application of purple phosphorus-based materials in multiple fields such as energy storage, electronic devices, and catalytic reactions.
