My team focuses recently on the design and fabrication of new functional porous materials to expand the application of selective adsorption and catalysis in chemical, energy and environmental protection.

Increasing the utilization of resources and inhibiting environmental pollution has prompted people to focus on the green chemistry to improve the atomic economy of chemical production and expand the selective catalytic process as much as possible. Since adsorption is the initial step of catalytic process, development of new materials for selective adsorption is very important for the study of green chemistry, which involves not only the design and synthesis of new structural molecular sieve, but also the understanding of selective adsorption itself.Here the selective removal of tobacco specific nitrosamines (TSNA) from tobacco was carried out in my team for many years because this subject is a famous nightmare in adsorption due to the complex composition of tobacco that contains thousands of components. Rather, we treated this challenge as the ideal platform to explore the application of selective adsorption in new fields. How to lock up the TSNA in hundreds of compounds and capture them within the channels of sorbent?How to increase the efficiency of TSNA capturer? How to endow non-ordered porous materials the function of selective adsorption?these challenges have to face and to be conquered.

Here are some research contents:

[1] Exploring new applications of zeolites in life sciences

Based on the discovery of insert-adsorption model of nitrosamines in zeolites, we try utilizing the special shape-selective adsorption of zeolites to block the metabolic pathway of carcinogens in the gastrointestinal system, eliminating the potential carcinogenic hazards in human body. Foe this aim, zeolite should play the role of selective sorbent and controllable releaser at the same time, for instance it should release nitric oxide then capture nitrosamines in gastrointestinal system.

[2] Development of new molecular sieve materials such as solid super-base

To meet the requirement of fine chemical industry or environment protection, it is necessary to prepare new functional materials like the super-bases with the selective adsorption capability. We plan to modify porous or coarse supports with metal salts or organic compounds through delicate methods such as multi-layer coating to control their distribution in the channel or pores. The resulting composites should have the pore structure of the host material and the specific catalytic or adsorption properties of the guests, in order to catalyze the synthesis of fine chemicals, or capture CO₂ at a relatively high temperature such as 473 K in flue gas.

[3] Molecular sieves removing carcinogens from tobacco smoke and tobacco products

To apply the selective adsorption and catalysis of zeolites to reduce the harm of tobacco products and protect environment, we will choose the optimal zeolites or mesoporous silica as the candidate after assessing the influence of their pore structure and surface composition on the adsorption. In addition, we will try to fabricate new sorbent with non-ordered porous materials, especially the porous carbon composites. The complex composition of tobacco smoke or tobacco extract solution, which contains hundreds of components, is obviously a challenge facing the selective adsorption of carcinogens like nitrosamines. Once we get the efficient sorbent, the research will be expanded to remove other environment pollutants such as phenol, formaldehyde, 1, 3-butadiene and nitrogen oxides. In recent years, liquid adsorption of tobacco specific nitrosamines (TSNA) becomes the main task in order to meet the requirement of removing TSNA in Snus and smokeless new tobacco products.

My group pursues innovation and application as the aim of scientific research and prepares many new functional materials to meet the requirements of chemical industry and environment protection. We published 228 papers, 39 reviews and 130 papers of symposium proceeding to date, applying the national invention patent 16 and among them 11 items were authorized. For the first time, we prepared the superbases in China, including some strong basic or superbasic zeolites and mesoporous silica materials. In addition, we revealed the “insert-adsorption” model in the capture of nitrosamines by zeolites, by which some new cigarette additives were developed to control the smoking-caused pollution and the corresponding patent had been transferred. In addition, my team had cooperation on related topics with BAT, Hongta Tobacco group and Shanghai Tobacco group.
