Abstract

Tetra- tert-butyl substituted FePc(acac) complexes were supported upon mesoporous molecular sieves MCM-41 and SBA-15 via adsorption and coordination bondings as well as by covalent grafting. Prepared materials were characterized by UV–vis, MALDI, N 2-BET, SEM, TEM, FTIR, 13C, 29Si NMR and DSC–TG techniques. Supported FePcs exhibited high activity in liquid-phase oxidation of phenol with H 2O 2. The most resistant towards oxidative degradation were shown to be the covalently grafted FePc species.
