卟啉钴分子筛的制备,表征和催化性能的研究

用液－固相分步合成法将新型四卤四甲基卟啉诱捕在经Ｃｏ＾２＋交换的ＮａＸ分子筛超笼内，利用索式提取器洗净分子筛外表面吸附的卟啉后，采用ＵＶ－Ｖｉｓ、ＩＲ、ＳＥＭ、ＤＴＡ、Ｘ射线衍射分析、吸附等手段对诱捕在超笼内的卟啉予以表征。进一步对比研究了卟啉、分子筛和诱捕卟啉分子筛的催化性能。结果表明，卟啉与分子筛结合后，催化活性大大提高。

Immobilization and Characterization of Porphyrin and Study of Its CatalyticCapability

A stepwish synthesis method was used to encapsulate tetrahalogen-tetramethyl porphyrins in the supercages of NaCoX molecular sieve,The resulting samples were washed with DMF in a Soxhiet extractor untill the porphyrin which deposited on the external surface of molecular sieve was removed completely.Charaterization of TCTMP and TBTMP was made by the methods of UV-Vis,IR,SEM,DTA and absorption.Catalytic capabilities of porphyrin,molecular sieve and NaCoX molecular sieve with supercage structure in which porphyrin was entrapped were compared.
