Catalytic oxidation is one of the most important technology for highly efficient and environment-friendly removal of industrial volatile organic compounds (VOCs).Typical industrial Cl heteroatoms-contained VOCs with highly toxical and stable property are selected in this project. Regarding the shortcomings of traditional noble metal/transition metal catalytic materials for CVOCs destruction，the approach for novel and highly efficient rare earth-double perovskite/molecular sieves composite catalysts, which combine the advantages of high-abundance rare earth, double perovskite and molecular sieves, controllable synthesis and nano active sites construction will be developed. Catalyst physicochemical properties regulation rule and active oxygen transfer feature will be demonstrated by oxygen isotopic exchange and advanced characterization techniques, and the pollutant oxidation behavior and adsorption-activation mechanism will also be illuminated from the molecular level through in situ methods and simulation. The pollutant oxidation routes and reaction products distribution regulation law will be constructed via catalyst pgysicochemical property and reaction condition optimization. The tolerance of the composite catalyst to water and chlorine species will be real-time studied to reveal the chlorine species adsorption/desorption characteristics, the catalyst deactivation process and the stability enhancement mechanism. This is a cross project involving the regions of porous materials and VOCs pollution control. The implementation of the project will provide new ideas and research basis for industrial CVOCs control, and further promote the technology innovation and progress for industrial VOCs economic and highly-efficient control.
