Because of their special physicochemical properties, pore-structured metal oxide catalysts are widely used in environmental catalysis, energy chemicals, fuel cells, medicine, and other related fields. In recent years, these oxides have also been increasingly studied the catalytic purification diesel engine exhaust gases. this paper, research progresses preparation methods porous application were reviewed. The advantages disadvantages different for synthesis elaborated, as well mechanism comparison types pollutants. Finally, current issues on development trends summarized discussed. beneficial improving contact efficiency between pollutants, which can enhance catalysts. Meanwhile, intrinsic activity is most fundamental factor determining except structure effects. addition, paper help researchers to deeply understand important effect treatment pollutants provide theoretical guidance design high-efficiency

Cu-ZSM-5 zeolites exhibit promising NH3-SCR activity in a wide temperature window. The current challenges preparing are reducing the cost and simplifying preparation process. one-pot method using Cu-amine complex as template is an excellent strategy for solving above problems. However, still lacking Cu-ZSM-5. In this work, Cu-(EDA)2 developed to prepare Cu-ZSM-5-O catalyst. According fundamental measurements, high dispersion of copper(II) species, appropriate acidity, Cu+ species favor reaction. Among catalysts, Cu1.8-ZSM-5-O shows performance at low temperatures (NO conversion about 87.5% 150 °C N2 selectivity 95% over entire window). boosting catalysts probably assigned abundant [Cu(OH)]+ amounts Cu-ZSM-5-O. Moreover, variable-temperature EPR subsequent computer simulation used first quantify content mechanism (150 °C) on also investigated by situ DRIFT spectra DFT calculations, which mainly follow Eley–Rideal route. A complete catalytic cycle SCR reaction was proposed based calculations. Our results suggest that contribute adsorption activation NH3, thus performance.

Nitrogen oxides emitted from diesel vehicle exhaust seriously endanger the atmospheric environment and human health, which have attracted people’s attention. Among numerous nitrogen oxide (NOx) removal technologies, photocatalytic of NOx SCR received widespread The treatment technology is a good choice due to its mild reaction conditions low costs. Moreover, NH3-SCR has been widely used in denitration plays an important role controlling emissions. In technology, development high-efficiency catalysts part. This paper summarizes research progress metal for reactions, including V-based catalysts, Mn-based Fe-based Ce-based Cu-based catalysts. Meanwhile, detailed process was also introduced. addition, this describes possible SO2 poisoning mechanism stability Finally, problems prospects were proposed.
