▎ 摘　　要

NOVELTY - Graphene-supported copper/zinc oxide catalyst comprises 5-10 wt.% copper as supported amount, where the molar ratio of copper to zinc oxide is 2:1-1:2 respectively, and the rest is graphene as carrier. USE - Graphene-supported copper/zinc oxide catalyst used as a dehydrogenation catalyst for catalyzing methanol dehydrogenation one-step preparation of methyl formate (claimed). ADVANTAGE - The graphene-supported copper/zinc oxide catalyst ensures high selectivity for the product methyl formate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene-supported copper/zinc oxide catalyst, which involves: (A) preparing an ammonia solution for use; and (B) preparing copper(II) nitrate trihydrate and zinc nitrate hexahydrate into a mixed aqueous solution for use.
