▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide gas gel loaded nano metal particles comprises (i) mixing the graphene oxide aqueous dispersion with the sodium alginate aqueous solution to obtain a mixed dispersion, where the concentration of sodium alginate is 2-8 mg/ml; (ii) adding an aqueous solution of a salt of a divalent metal ion into the mixed dispersion to carry out a crosslinking reaction to obtain a hydrogel; (iii) freezing and drying the hydrogel to obtain the sodium alginate gas gel chelated and cross-linked by graphene oxide and metal ions; and (iv) subjecting the sodium alginate gas gel to a heating reduction reaction at 600-1200℃ under an inert gas to obtain the reduced graphene oxide gas gel loaded with nano metal particles. USE - The method is useful for preparing reduced graphene oxide gas gel loaded nano metal particles. ADVANTAGE - The method prepares reduced graphene oxide gas gel loaded nano metal particles with improved catalytic efficacy and utilization of metal components and reduced metal consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for reduced graphene oxide gas gel loaded nano metal particles.
