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/desorption isotherms, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, diffuse reflectance ultraviolet-visible spectroscopy, thermogravimetric 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 naphthalene with meta-chloroperbenzoic acid as the oxidant. The catalyst could be reused several times without loss of its activity.
Graphical AbstractPolyhalogenated manganese porphyrins with fluorine substituents were anchored on amino-functionalized MCM-41 to produce a heterogeneous catalyst, which exhibited remarkable catalytic activity and desirable reusability in the hydroxylation of naphthalene.Figure optionsDownload as PowerPoint slide
