| 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, TPR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: | Abstract The selective catalytic reduction (SCR) of NO with 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, IR and ESR. The results show that the copper ions (Cu2+and Cu+ ) coordinated with framework aluminium are a main active centre for SCR of NO over CuCl/AlMCM-41 catalyst, whereas in CuCl/SiMCM41 catalyst these kinds of copper ions could not been found. |
