| Abstract | Upward environment awareness in recent years has caused institution of more and more series regulation. NOx is one of the major air pollutant which may harm human, animal, vegetation and environment. Catalysts in vehicles exhaust play an important role in reduction of NOx [1]. A large number of researches have been done in the field of hydrocarbon as reductant for selective catalytic reduction of NOx in oxygen rich conditions. But it is found that practical applications of hydrocarbon SCR has been difficult due to poor performance in real life application. So researchers are currently focusing on H2-SCR, which gives well performance at low temperature <200°C [2]. The preferred way for reduction of NOx in diesel engine exhausts, requisite catalysts which operate in broad temperature windows (60-450°C). Besides metal oxides catalysts, ZSM-5 based catalysts have high activity and wide temperature window. ZSM-5 is one of the zeolite which have strong solid acidity is generated by aluminium atoms incorporated into the tetrahedral site framework [3]. |
