Heterogenized Fe(III) phthalocyanine: Synthesis, characterization and application in liquid-phase oxidation of phenol

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, 13 C, 29 Si NMR and DSC–TG techniques. Supported FePcs exhibited high activity in liquid-phase oxidation of phenol with H 2 O 2 . The most resistant towards oxidative degradation were shown to be the covalently grafted FePc species.
