The invention adopts an electrochemical assisted method to prepare perforated black phosphorene material; the method of the invention is simple and easy, and the prepared perforated black phosphorene will have a larger Specific surface, more reactive sites, and higher ion transport efficiency have good application prospects in the fields of energy storage, catalysis, and gas membrane separation.

Description

technical field [0001] The invention relates to a method for preparing a perforated black phosphorene material, belonging to the technical field of nanomaterial preparation. Background technique [0002] Black phosphorus is a new type of semiconductor material. Due to its unique anisotropy, high carrier mobility, large on-off ratio and other excellent properties, it has a good application prospect in many fields. Because nano black phosphorus has better performance than bulk black phosphorus, black phosphorus is usually nanosized in various application fields; studies have shown that different forms of nano black phosphorus will have different properties and application fields. Therefore, the development of a new type of nano black phosphorus and its preparation method is expected to further improve the performance of nano black phosphorus and broaden the application field of nano black phosphorus. [0003] As a new type of nano-black phosphorus, perforated black phosphoren...
