Heterogenized Fe(III) phthalocyanine: Synthesis, characterization and application in liquid-phase oxidation of phenol
摘要:
Tetra-tort-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, C-13, Si-29 NMR and DSC-TG techniques. Supported FePcs exhibited high activity in liquid-phase oxidation of phenol with H2O2. The most resistant towards oxidative degradation were shown to be the covalently grafted FePc species.
