▎ 摘  要

NOVELTY - Composite copper-based composite material comprises an intercalation compound and a copper-oxide-copper heterojunction loaded on the intercalated compound. The intercalating compound includes a melon ring and a reduced graphene oxide. The melon rings intercalate the graphene oxide to reduce the amount of oxide. USE - The multi-element copper-based composite material is useful in electrochemical process for producing ethylene, acetic acid and ethanol. ADVANTAGE - The method is featured with simple synthesis, convenient operation, wide application range, and the preparation condition is mild, the method is simple, without special device. The space effect generated by the melon ring rigid structure and the hydrophobic cavity structure can form stable hydrophilic diffusion layer. The method effectively inhibits the corrosion of the electrolyte to the Cun + and improves the stability of the catalyst. In addition, using the main body chemical of the cucurbit ring, capable of specifically absorbing CO 2 molecules, increasing the local CO 2 concentration of the Cu2O-CuO metal interface, partially reducing the graphene oxide (rGO) to collect the current, improving the activity of catalyst. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of polynary copper-based composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a powder X-ray diffraction image of the Cu2O-CuO/CB 6 /rGO of the multi-copper-based composite material Cu2O-CuO/CB 6 /rGO prepared by the embodiment 1.
