▎ 摘　　要

NOVELTY - Preparing monodisperse iron oxide/graphene oxide composite material by inducing organic matter comprises (i) dissolving iron salt in solvent A to obtain iron source solution, (ii) dissolving organic matter in solvent B to obtain an organic matter solution, (iii) mixing the organic solution and the graphene oxide dispersion to obtain slurry, adding the iron source solution to the slurry and mixing to obtain a reaction precursor, (iv) placing reaction precursor liquid in a hydrothermal reaction kettle for hydrothermal reaction, and washing, filtering, and drying after the reaction to obtain a solid composite and (v) placing solid composite in a tube furnace and calcined in an inert atmosphere to obtain material. USE - The preparing monodisperse iron oxide/graphene oxide composite material by inducing organic matter is useful in catalytic Fischer-Tropsch synthesis (claimed). ADVANTAGE - The method: has simple preparation, easy operation, good repeatability, and easy-to-obtain raw materials. The material is suitable for large specifications produce and economical. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for monodisperse iron oxide/graphene oxide composite material.
