▎ 摘　　要

NOVELTY - Preparing purple phosphorus-based photocatalytic material, comprises dispersing purple phosphorus nano material and two-dimensional material in organic solvent, ultrasonic processing, filtering, washing and drying to obtain final product. USE - The purple phosphorus-based photocatalytic material is useful in photocatalytic water splitting to produce hydrogen (claimed). ADVANTAGE - The purple phosphorus-based photocatalytic material: constructs purple phosphorus into a 2D/2D composite material, which is first in terms of material composition; can self-assemble through mutual attraction under the condition of solvent ultrasonic assistance to form tighter composite structure; and has better catalytic activity and higher stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for purple phosphorus-based photocatalytic material prepared by above method.
