▎ 摘　　要

NOVELTY - Producing graphene loaded metal oxide nano-material, comprises (a) ultrasonically dispersing the graphite oxide in distilled water at 30-50?OC to prepare suspension, (b) adding acetylacetone metallic compound into the suspension at 60-80 degrees C, stirring for 1-4 hours, and transferring to polytetrafluoroethylene lined hydrothermal kettle, and (c) placing the hydrothermal kettle in an oven at 140-180 degrees C for hydrothermal treatment for 12-48 hours, taking out the hydrothermal kettle, naturally cooling, filtering, washing and drying to obtain nano material. USE - The graphene loaded metal oxide nano-material is useful as catalyst for reduction activation in Fischer-Tropsch synthesis reaction (claimed). ADVANTAGE - The method comprises hydrothermal treatment, thus enables uniform dispersion of small size nano-oxide particles in graphene microstructure; produces graphene loaded metal oxide nano-material having high stability and high gasoline section (5-11C) hydrocarbon selectivity in comparison with modified iron catalyst. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene loaded metal oxide nano-material obtained by the above method.
