The invention relates to the technical field of photocatalyst preparation, and particularly relates to a composite material composed of an ultra-thin black phosphonene non-metal promoter, a preparation method and a cocatalyst. Low temperature pretreatment with liquid nitrogen is beneficial to ultrasonic assisted liquid phase stripping of layered materials, improving stripping efficiency, preparing high quality and high yield ultrathin black phosphorus ene nanosheets; and preparing ultrathin black phosphorus ene nanosheets as a non- The metal promoter material can form a strong electronic coupling with the photocatalyst material, facilitates rapid migration of photogenerated charges, and provides a large specific surface area, exposes more active sites, and has good photocatalytic performance. |
