NOVELTY - Preparing high-efficiency synthetic black phosphorus catalyst comprises (1) mixing phosphorus iodine tin catalyst powder and auxiliary agent, grinding uniformly according to a certain mass ratio, (2) adding the uniformly grinded mixture in the step (1) into a mold and pressing for a period of time to form the mixture, (3) using the step (2) to obtain the formed and auxiliary agent-containing catalyst after high temperature curing for preparation of black phosphorus, and under the same condition circularly using catalyst for at least five times. USE - The method is useful for preparing high-efficiency synthetic black phosphorus catalyst. ADVANTAGE - The method can greatly improve the mechanical performance and heat conducting performance of the catalyst, so as to increase the catalyst for preparing black phosphorus conversion rate and cycle times, is simple, economical and the catalyst has high yield, high crystallinity and high purity, can be widely used for energy storage, catalysis and other fields and it lays the foundation for low cost and large-scale preparation of black phosphorus.
