▎ 摘　　要

NOVELTY - Preparing high dispersing carbon dioxide hydrogenation catalyst by using copper iron oxide doped graphene oxide (GO) as a precursor comprises (i) mixing the iron salt and the copper salt in a solvent to form a uniform solution, adding a precipitant into the solution, and stirring until the precipitant is completely dissolved to obtain a suspension, (ii) adding graphene oxide into the suspension, uniformly stirring, and adding a reducing agent to obtain a solution system, and (iii) hydrothermally reacting the solution system to obtain the finished product. USE - The hydrogenation catalyst is useful as a carbon dioxide hydrogenation liquid fuel catalyst (claimed). ADVANTAGE - The catalyst: has short preparation cycle, simple and easy-to-obtain raw materials, short reduction time, and high carbon dioxide conversion rate and hydrocarbon selectivity for the reaction of carbon dioxide hydrogenation to liquid fuel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a high dispersing carbon dioxide hydrogenation catalyst by using copper iron oxide doped GO as a precursor prepared by the above-mentioned method.
