Iron-substituted aluminophosphate molecular sieves (FeAPO-5) were synthesized by hydrothermal crystallization and characterized with XRD

SEM

FT-IR and UV-Vis techniques.The results showed that the synthesized samples had good crystallinity and uniform grain.From the obtained characterization results

it could be concluded that both the framework and extra-framework Fe species were together present in the FeAPO-5 samples

and most iron ion was incorporated into the AlPO4-5 framework.FeAPO-5 as a heterogeneous catalyst is effective for catalytic oxidation of phenol in aqueous solutions with H2O2 as oxidant.The best results (99.0% phenol conversion

77.8% total organic carbon) after 240 min at 80℃ were obtained with phenol initial concentration 200 mg·L-1

H2O2 initial concentration 1200 mg·L-1 and pH5.0. Meanwhile

inductively coupled plasma (ICP) spectrometry results indicated that the concentration of leaching-off Fe3+ in the solution was very little and the FeAPO-5 molecular sieves was stable in the process of catalytic oxidation of phenol in aqueous solutions.
