The environment-friendly elimination of industrial volatile organic compounds (VOCs) is a hot research topic in the field of air pollution control, and catalytic oxidation is one of the most important technologies for VOC removal. Industrial oxygenated VOCs (OVOCs) emitted from pharmacy, semiconductor, and package printing are selected in this project. Approaches for controllable synthesis of alkali metal-noble metal/hierarchical molecular sieve bicomponent materials which combined with the advantages of alkali metal, nanosize noble metal and hierarchical porous molecular sieve in catalytic reaction will be investigated and developed. The electronic transfer characteristic, oxygen transfer and activation feature, and physicochemical properties regulation rule of synthesized composite materials will be revealed by density functional theory (DFT) calculation and advanced characterization techniques, and the role of catalyst acid/basic sites and oxidation kinetics and activation mechanism of OVOCs will be illuminated from molecular level by using in situ characterization and surface reaction techniques and simulated calculation. Based on the above results, the adsorption and activation rules and interaction mechanism of multiple OVOCs will be determined. The efficient control of reaction byproducts will be achieved through physicochemical property and reaction condition optimization. The oxidation activity, product selectivity, hydrothermal stability, and coke resistance of synthesized catalysts will be studied systematically under simulated operation conditions in order to reveal the optimization mechanism of catalyst performance. The research will provide new ideas, new materials, and scientific basis for industrial VOC control, which have important theoretical significance and practical value.
