▎ 摘　　要

NOVELTY - A graphene composite pipe with regular geometric shape is prepared by mixing solid carbon source with a metal catalyst particle, releasing the carbon atom from the solid carbon source by physical method, and forming the graphene composite pipe with regular geometric shape in the function of the metal catalyst or by heat treatment and fast cooling methods. The size of the pipe diameter is 2-2000 mu m and the length of the pipe is 5 nm-1000 mm. USE - Method for preparation of a graphene composite pipe with regular geometric shape (claimed) used in electrode material of lithium ion battery, biochemical detector, hydrogen storage material, and photoelectric device. ADVANTAGE - The carbon structure has the specific surface area more than the graphene, and is made of the graphene single crystal.
