“…Many power plants, steel mills, and other factories have used wet flue gas desulfurization to efficiently remove SO 2 , nevertheless, NO x cannot be removed efficiently (Thasan Raju et al, 2008). During the past years, the selective catalytic reduction (SCR) of NO x with hydrocarbons received increased more attention as an effective method from both academic and industrial points of view, while various catalysts for this process, such as transition metal-loaded zeolites (Yvonne Traa et al,1999; M. Huuhtanen et al,2005), H-form zeolites (Yvonne Traa et al,1999) and alumina-based catalysts(Atsushi Satsuma and Ken-ichi Shimizu, 2003) have been reported. As the reductions, many reports have been published on the use of methane, propane, or propene (Resini C et al, 2003;Shibata J et al, 2003).…”

The selective catalytic reduction of nitric oxide by ethylene was studied over Cu/ZSM-5 catalyst in the temperature range of 200-550°C, in which NO cannot be reduced by ethylene without Cu/ZSM-5 catalyst. Prepared Cu/ZSM-5 catalyst in varies loading as Na/ZSM-5 by the wet impregnation method, and the effect of the catalytic activity was studied in varies fitting temperatures. Several influencing factors, such as the different reaction temperatures, oxygen gas concentration, and Cu2+ concentration were investigated. Cu-Ce-ZSM-5 catalyst was prepared by wet impregnation method and the metallic influence of CeO2 to the catalytic ability was studied.

Rigorous regulations of nitrogen oxide emissions require the development of technologies for their removal from exhaust gases. Implementation of appropriate catalysts can potentially promote NO x (NO, NO 2 ) or N 2 O removal in shorter reaction time and under milder operation conditions. However, several challenges have to be faced upon trying to address nitrogen oxide pollution with catalytic systems such as sufficient catalytic performance, suitable operational temperatures and catalyst poisoning. The flexible structure of hydrotalcite-like compounds offers the opportunity to introduce various metals into the materials to provide active and selective catalysts for NO x and N 2 O removal. This minireview summarizes the abatement of nitrogen oxides by using hydrotalcite-derived mixed metal oxides. At first, a brief overview on the general features of hydrotalcite-originated mixed metal oxides and their applications in catalysis is provided. Later on, the application of mixed metal oxides as SCR catalysts with both ammonia (NH 3 -SCR) and hydrocarbons (HC-SCR) as reducing agents is discussed. An overview of the mixed metal oxides applied as catalysts for NO x storage/reduction (NSR) and further in the simultaneous removal of NO x and soot particles is provided. Additionally, this review discusses mixed metal oxides as efficient catalysts for catalytic decomposition (deN 2 O) and selective catalytic reduction of N 2 O (N 2 O-SCR). Finally, the remaining challenges and future trends are highlighted.
