氨功能化介孔MCM-41固载锰卟啉作为萘羟基化多相催化剂

将不同含量的四(五氟苯基)卟啉锰固载于表面氨基功能化的MCM-41介孔分子筛，所得样品通过粉末X射线衍射、氮气吸附脱附、傅里叶变换红外光谱、X射线光电子能谱、扫描电子显微镜、漫反射紫外-可见光谱、热重和差示扫描量热、电感耦合等离子体进行了表征.结果表明，四(五氟苯基)卟啉锰通过Mn与氨基的轴向配位固载于MCM-41.所制备的样品作为多相催化剂在以间氯过氧苯甲酸为氧化剂选择氧化萘反应中表现出良好的催化性能，且多次使用后没有明显的活性损失.

Coordination of manganese porphyrins on amino-functionalized MCM-41 for heterogeneous catalysis of naphthalene hydroxylation

The different amounts of [5,10,15,20-tetrakis-(pentafluorophenyl)porphyrin] manganese chloride (TF20PPMnCl) were immobilized on amino-functionalized MCM-41 for catalysis of the hydroxylation of naphthalene. The samples were characterized by X-ray powder diffraction, N2 adsorption/de-sorption isotherms, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, diffuse reflectance ultraviolet-visible spectroscopy, thermogravimet-ric and differential scanning calorimetry, and inductively coupled plasma mass spectrometry. The results indicated that the manganese porphyrins were axially coordinated on amino-functionalized MCM-41.The prepared samples showed remarkable catalytic activity in the hydroxylation of naph-thalene withmeta-chloroperbenzoic acid as the oxidant. The catalyst could be reused several times without loss of its activity.
