Photocatalytic oxidation desulfurization by iron phthalocyanine supported on Ti-MCM-41
Titanium-silicium molecular sieve Ti-MCM-41 was synthesized and the iron phthalocyanines(FePcs) with different substituent groups were loaded onto the modified Ti-MCM-41 by covalent bond to prepare FePcs(R)/Ti-MCM-41 catalyst. FePcs(R)/Ti-MCM-41 were characterized by FT-IR
XRD
SEM
BET and UV-Vis DRS. Dibenzothiophene(DBT) was photo-oxidized with FePcs(R)/Ti-MCM-41 as photocatalysts
air as oxidant and CPL-CTAB ionic liquid as extraction agent in the irradiation of visible light under room temperature and atmosphere. The optimal reaction conditions were explored by simple variable method. The results showed that FePc(NH2)/Ti-MCM-41 exhibited a better photocatalytic activity and the removal ratio of DBT was up to 95.6% under the optimal reaction conditions. The catalytic performance of FePc(NH2)/Ti-MCM-41 did not decrease obviously after reusing 5 runs of oxidation.
