▎ 摘　　要

NOVELTY - Preparation method of ionic liquid (IL)/graphene oxide (GO)/iron-based metal organic frameworks (MOFs) composite photocatalytic material, involves (a) dissolving ionic liquid, soluble iron salt, organic ligand, and graphene oxide in a solvent to obtain a reaction mixture, and (b) heating the reaction mixture to obtain IL/GO/iron-based MOFs composite photocatalytic material. USE - The method is used for preparation of ionic liquid (IL)/graphene oxide (GO)/iron-based metal organic frameworks (MOFs) composite photocatalytic material in the degradation of pollutants (all claimed). The material is used for removing tetracycline, ibuprofen, and bisphenol A molecules in water. ADVANTAGE - The photocatalytic material improves the adsorption performance, enriches tetracycline, ibuprofen, and bisphenol A molecules in water, has excellent photocatalytic performance and water stability. The photocatalytic material efficiently removes tetracycline, ibuprofen, and bisphenol A molecules in water and can be reused. The method has simple and environmentally-friendly preparation process and has low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of the IL/GO/iron-based MOFs composite photocatalytic material in the degradation of pollutants.
