▎ 摘  要

NOVELTY - Preparing composite carbon catalytic material, comprises using graphene oxide and a carbon rod composite carbon material as a catalyst carrier, and using ruthenium (Ru) as an active component, and the carbon rod is intercalated on the graphene oxide sheet, between, the length of the carbon rod is 10-20 mu m, the diameter is 0.5-0.7 mu m, the specific surface area of the graphene oxide and carbon rod composite carbon material carrier is 289-357 m2/g, and the mesopore diameter is 5-10 nm, the carbon rod is prepared by (1) using aluminum as the substrate, a porous oxide film is formed on the surface of the aluminum by electrochemical methods; (2) using porous oxide film as a hard template and using pitch resin polymer as the carbon source, the carbon source is repeatedly filled in the oxide film pores; (3) mechanically polishing material; (4) removing hard template from the material by strong acid etching; and (5) washing, drying and dissolving to obtain an aqueous solution of carbon rods. USE - The method is useful for preparing composite carbon catalytic material. ADVANTAGE - The method can effectively separate the agglomeration of graphene oxide, significantly increase the specific surface area of graphene oxide, and can be used as a catalyst carrier, and is suitable for PROX gas-solid phase catalytic reaction under hydrogen-rich conditions. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the method for preparing composite carbon catalytic material.
