Progress in Structure and Catalysis Properties of ZSM-5 Zeolites
【摘要】 探究了ZSM-5分子筛的晶体结构、孔结构及酸性质;对通过离子交换对其表面进行优化以提高催化活性方面的研究工作进行了阐述;对Cu-ZSM-5分子筛上NO直接催化分解反应提出了:4CuO=2Cu2O+O2,2Cu2O+4NO=4CuO+2N2+O2的反应机理。
【Abstract】 The progress in the crystal structure,catalysis and acidic properties of MZSM-5 was summarized briefly.The effective three-dimensional channels were studied.Copper cation exchanged ZSM-5 zeolites are effective catalysts for the NO decomposition reaction.The redox mechanism has proposed as follows:4CuO=2Cu2O+O2 2Cu2O+4NO=4CuO+2N2+O2
