▎ 摘  要

NOVELTY - Preparing graphene oxide aerogel densely coated zinc cobaltate complex comprises (i) ultrasonically dispersing zinc cobaltate particles in graphene oxide suspension to form a uniform and stable mixed system, placing in a reaction kettle and heating for a specific period of time, (ii) performing fast cooling, (iii) filtering, washing, and fastly drying to obtain low water content of graphene oxide aerogel compact coating zinc cobalt complex, and (iv) subjecting the complex obtained in the step (iii) to vacuum freeze drying to obtain the finished product. USE - The method is useful for preparing graphene oxide aerogel densely coated zinc cobaltate complex. ADVANTAGE - The method: maintains dense and porous stable structure of graphene oxide aerogel on the surface of the zinc cobalt oxide catalyst crystal; has multivariate transition metal catalytic properties of zinc cobaltate combined with large specific surface area and strong adsorption properties of graphene oxide aerogels; maximizes conductivity and catalysis, and synergistic catalysis; is simple; and easily separates the product. The product: has dense coating layer structure, which is not easily changed during production and processing; and is easy to amplify production and applied to actual production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide aerogel densely coated zinc cobaltate complex prepared by the above-mentioned method.
