▎ 摘　　要

NOVELTY - Microwave-assisted preparation of metal oxide/graphene nanostructured material, is claimed. The nanostructured material adopts reduced graphene oxide nanosheets as matrix, and the reduced graphene oxide nanosheets are loaded with a second-phase metal oxide, where the second-phase metal oxide is indium(III) oxide, iron(III) oxide, cobalt tetraoxide and/or zinc oxide. The second-phase metal oxide is appear as particles or clusters with a size of 3-50 nm on the reduced graphene oxide nanosheets. USE - Used as microwave-assisted preparation of metal oxide/graphene nanostructured material. ADVANTAGE - The method: utilizes reduced graphene oxide as matrix to load the introduction of second-phase metal oxide particles or strip clusters which support for the spatial blocking of graphene; reduces stacking and curling between graphene sheets; prevents agglomeration of second-phase metal oxide particles and thus produces large specific surface area; and improves gas sensitivity and other related properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing metal oxide/graphene nanostructured material, comprising (i) dissolving soluble metal salt in graphene oxide solution and stirring to obtain uniform suspension, (ii) irradiating obtained suspension in a microwave oven, naturally cooling to room temperature, centrifuging, separating and collecting precipitate and washing precipitate using deionized water for 3-6 times to obtain washed product, and (iii) freeze-drying washed product to obtain intermediate, and calcining obtained intermediate under vacuum to obtain final product.
