摘要：
Copper-modified MCM-41 functional materials could be directly synthesized through "in situ coating" process by adding cupric salt precursors in the acidic synthetic system. Incorporation of copper in MCM-41 affected the ordering of mesostructure and enhanced the catalytic activity, due to the formation of CuO-like species and abundant oxidation and/or coordination states of copper, exhibiting higher activity than the corresponding modified SBA-15 samples in the temperature programmed surface reaction (TPSR) of N-nitrosopyrrolidine (NPYR).
