摘要： 研究了由分散法制备的两种CuCl/MCM－41催化剂上丙烯在过量氧存在下选择催化还原NO反应,发现所制备的CuCl/AlMCM－41催化剂的反应活性明显高于CuCl/SiMCM－41.XRD,IR,TRR及ESR的研究结果表明,CuCl/AlMCM-41催化剂上的主要活性中心是与骨架铝配位的铜离子(Cu2+/Cu+).

Abstract: The selective catalytic reduction (SCR) of NOwith propene over CuCl/AlMCM-41 and CuCl/ AlMCM-41 catalysts prepared by dispersion method was studied.It was found that CuCl/AlMCM-41 exhibits a substantially higher catalytic activity over CuCl/SiMCM-41.And the function of copper species in these catalysts was also investigated by means of H2-TPR, IRand ESR.The results show that the copper ions (Cu2+and Cu+ ) coordinated with framework aluminium are a main active centre for SCRof NOover CuCl/AlMCM-41 catalyst, whereas in CuCl/SiMCM41 catalyst these kinds of copper ions could not been found.

Key words: CuCl/MCM- 41, NO, Selective catalytic reduction
