Heterogeneous Catalysis

更新时间:2012-01-17 11:12:05

The heterogeneous catalysis is of significance to suppress the air pollutants like NOx, CO, HC, PMetc, resulting from vehicle exhaust emission, stationary power plant, etc.. When these pollutants emit into the atmosphere, they will cause serious air pollution to the environment and threaten human health. In our lab, we combine DFT based simulations, statistical database, experimental synthesis and characterizations to efficiently design highly active non-precious metal oxide catalysts. Through the rational design scheme, we explore how to shorten the catalyst R&D period significantly. Specifically, we design mullite-based catalyst for the oxidation of hydrocarbons, black soot, NH3, etc.
