ZVZ composite material, preparation method thereof and method for degrading halogenated organic matters

The invention provides a ZVZ composite material for degrading halogenated organic matters, a preparation method of the ZVZ composite material and a method for degrading halogenated organic matters. The ZVZ composite material comprises a CaAlLDH layered compound, ZVZ and PEG, wherein the PEG wraps the ZVZ layered compound and the CaAlLDH layered compound, and the ZVZ composite material is named asPEG@Ca-Al-LDH-ZVZ. The ZVZ composite material disclosed by the invention can stably exist in air, the reaction activity of the ZVZ composite material can be activated by adding ascorbic acid when theZVZ composite material is used for reductive degradation reaction of halogenated organic matters so as to reduce passivation of the ZVZ composite material in preparation, transportation and use processes; therefore, a PEG@Ca-Al-LDH-ZVZ and AA system can efficiently, quickly and thoroughly degrade the halogenated organic matters. 本发明提供一种用于降解卤代有机物的ZVZ复合材料及制备方法、降解卤代有机物的方法，所述ZVZ复合材料包括：Ca-Al-LDH层状化合物、ZVZ和PEG；其中，所述PEG包裹ZVZ和Ca-Al
