“…The Cu (Cl)/ZSM-5 catalyst had the highest activity among these catalysts. Its activity increased with temperature, remaining constant until about 300 • C, and then weakened with a small slope [50]. At the same time, Wang's team [51] found that an excellent Cu/ZSM-5 catalyst was prepared by a polymer-assisted deposition method.…”

“…Marzieh Hamidzadeh proved that the hydrothermal impregnation of cobalt chloride and nitrate on HZSM-5 enhanced its denitrification catalytic activity. The Co (Cl)/ZSM-5 catalyst showed the highest activity around 300 • C [50]. However, the related research is very limited since many previous works focus on the NO-SCR reaction over Co-containing H-ZSM-5 catalysts with a C x H y reductant instead of NH 3 [55].…”

Nitrogen oxides (NOx) are very common air pollutants that are harmful to the environment and human bodies. Selective catalytic reduction with ammonia (NH3-SCR) is considered an effective means to remove NOx emissions due to its good environmental adaptability, high catalytic activity, and remarkable selectivity. In this paper, the preparation methods, types, advantages, and challenges of ZSM-5 catalysts are reviewed. Special attention is paid to the catalytic properties and influence factors of ZSM-5 catalysts for NH3-SCR. The SCR performances of ZSM-5 catalysts doped with single or multiple metal ions are also reviewed. In addition, the environmental adaptabilities (sulfur resistance, alkali resistance, water resistance, and hydrothermal stability) of ZSM-5 catalysts are discussed, and the development of ZSM-5 catalysts in denitrification is summarized.

“…During the last decade, the catalysts based on zeolite indicated a perfect process for this reaction. Cu-Zn / ZSM-5 18 , Cu-Fe / ZSM-5 19 Cu / ZSM-5 20 are among the investigated catalysts which have a high capability for the removal of NO x . The previous studies have mainly focused on the changes of the active component, synthesis and calcination temperature.…”

Selective catalytic reduction of nitrogen oxide with ammonia in the presence of excessive oxygen was investigated on transition metal oxides' catalysts (V, Cr, Mn, Fe) supported on HZSM-5. Meanwhile, catalyst V/ZSM-5 and Fe/ZSM-5 have shown the most activity and the conversion percentage of nitrogen oxides to nitrogen is more than 97% at temperatures above 300 °C, in these two catalysts. All synthesized catalysts possessed a good stability. Analytical characterization of synthesized catalysts were conducted by different methods of temperature programmed reduction, absorption and desorption of nitrogen, temperature programmed desorption of ammonia, X-ray diffraction and diffuse reflectance UV-vis spectroscopy. The less the apparent activation energy is, the more their activity will be. Thus, the Cr/ZSM-5 and V/ZSM-5 catalysts showed the lowest and highest performance in this process, respectively.
