## About

Aiming at the effective removals of series of N-containing waste gases, including (NOx, N2O, NH3, RCN) from industry, as well as classical indoor pollutants, such as formaldehyde and ozone; the related mechanisms on high selective transformation of these harmful compounds towards the target unharmful products were studied by means of both experimental DRIFTs & TPD techniques and theoretical DFT calculation to clarify the structure-performance correlation for better design of catalytic materials. Firstly, Cu-SSZ-13 was successfully synthesized by using a relatively cheap & new template of Choline Chloride, achieving an extraordinary deNOx performance with NO conversion of 95% across a broad temperature window of 150-450oC. Secondly, for the purification of N2O-containing exhaust from the industrial plant for adipic acid production with an annual yield of 250,000 tons, granular β-type zeolite catalyst was scale-up prepared based on the design of active sites via molecular simulation and thereafter utilized to reduce the N2O green-house gas of 20,000 tons per year. Thirdly, one-step technique on selective catalytic combustion of acrylonitrile was developed as well as an industrial system was established to eliminate the effluent nitrile gases with a total flow rate of 100,000 m3/h as a chair of National High-Technique Project (863 project).
