▎ 摘　　要

NOVELTY - The phosphide/graphene composite nano material includes a main component of molybdenum phosphide and carbon, and a nano-wire structure. The nano-wire surface is uniformly coated with a layer of graphene which forms a total of 2 to 3 layers. USE - Molybdenum phosphide/graphene composite nano material. ADVANTAGE - The preparation method for raw material or nano material are simple and easy to perform since the whole experiment process is simple. The operation is convenient and environment-friendly. It is easy to realize the large-scale production of the product and market popularization and application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method for graphene composite nanometer material. DESCRIPTION OF DRAWING(S) - The drawing shows an image for preparing the sample.
