▎ 摘　　要

NOVELTY - Preparing graphene-supported multi-metal nanowire aerogel composite material comprises (i) carrying out ultrasonic dispersion of graphene oxide, polymetallic nanowires, and reducing agents to obtain graphene oxide/polymetallic nanowire dispersion, (ii) transferring the obtained dispersion to a polytetrafluoroethylene (PTFE) high-pressure reactor, carrying out heat reaction, washing and removing impurities with deionized water to obtain graphene-supported polymetallic nanowire, and (iii) freeze drying the obtained graphene-supported polymetal nanowires. USE - The method is useful for preparing graphene-supported multi-metal nanowire aerogel composite material. ADVANTAGE - The method: is simple, inhibit the agglomeration of the multi-metal nanowires, improves distribution of the nanowires, and has larger specific surface area and higher reactivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-supported multi-metal nanowire aerogel composite material prepared by the above mentioned method.
