The composite of graphene and a perovskite-type oxide (PTO) should be an attractive new material, owing to the special properties of graphene and the flexibility of PTO. Both graphene and PTO are promising support for some metallic nanoparticles. Therefore, in this work, taking LaFeO 3 as the representative for PTO, a novel composite of graphene sheets-LaFeO 3 has been prepared by using hydrothermal synthesis, and bimetallic nanoparticles of Cu-Co have been loaded on the composite. The resultant catalyst is applied to higher alcohols synthesis (HAS) from syngas. The morphology, structure and the state of the bimetallic composite catalyst are characterized by using techniques of SEM, TEM, AFM, XRD, TPR, Raman and N 2 adsorption-desorption. For the graphene-LaFeO 3 support, the graphene sheets are embedded into the bulk LaFeO 3 or uniformly deposited on the surface of the LaFeO 3 grains, resulting in high specific surface area.And the mass transferring ability of the bimetallic catalyst is optimized by uniform mixing of graphene and LaFeO 3 and the formation of the mesopores. For the active component, the Cu-Co alloy nanoparticles are highly dispersed on the graphene-LaFeO 3 composite, which leads to the high activity, high selectivity and
