▎ 摘  要

NOVELTY - Preparation of graphene-loaded copper-zinc-aluminum catalyst involves (s1) dissolving graphene oxide in a solvent (A), adding monomer N-vinyl pyrrolidone (NVP) and an initiator into the system, raising temperature under the protection of nitrogen to initiate a polymerization reaction, dehydrating and drying after the reaction to obtain polyvinyl pyrrolidone (PVP)-grafted graphene, and (s2) dissolving the PVP-grafted graphene in a solvent (B), adding soluble salts of copper, zinc and aluminum, dispersing uniformly, heating, adding reducing agent to carry out reduction reaction, cooling and aging after the reaction, and calcining the aged precursor under the protection of inert gas. USE - Preparation of graphene-loaded copper-zinc-aluminum catalyst for use in reaction of synthesis gas to methanol (all claimed). ADVANTAGE - The method provides stable catalyst having high-catalytic efficiency when used in synthesis gas to methanol reaction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of graphene-loaded copper-zinc-aluminum catalyst in reaction of synthesis gas to methanol.
