▎ 摘　　要

NOVELTY - Use of graphene oxide/metal organic framework composite material is claimed in light-controlled desorption of volatile organic matter, where composite material is a graphene oxide/metal organic framework composite material, which is abbreviated as GO/MIL-101, and graphene oxide is ultrasonically dispersed in water to form graphene oxide (GO) suspension. The GO suspension and the Cr salt are added into a reaction kettle with polytetrafluoroethylene, uniformly stirred, added organic ligand terephthalic acid and water, heated at 160-220℃, carried out hydrothermal reaction for 6-16 hours, washed, and dried to obtain the catalyst. USE - Graphene oxide/metal organic framework composite material used in light-controlled desorption of volatile organic matter, such as ethyl acetate, toluene or styrene (claimed). ADVANTAGE - The composite material enables to widen and enhance the light absorption range and intensity of the MOF, and absorb a large amount of light energy and convert it into heat energy under the irradiation of light with a wavelength of 200-1200 nm, excite fast desorption of volatile organic compounds (VOCs) and regeneration of adsorbents. The composite material has simple process, fast desorption speed and low energy consumption, which is suitable for industrial production and has broad application prospects.
