Abstract

Iron-incorporated mesoporous silica materials (MFS-9) have been successfully prepared in strong acidic media by a two-step synthesis procedure, which has an hexagonal structure with uniform mesopores and exhibits superior hydrothermal stability and high catalytic activities for the hydroxylation of phenol and also of bulky trimethylphenol. Xray diffraction data show that mesoporous ferrisilicate (MFS-9) can retain its mesoporous structure in boiling water up to 100 h. Characterization of MFS-9 by a variety of spectroscopic techniques, including electron spin resonance, UV- vis and UV-Raman spectroscopies, suggests that Fe species in the framework of MFS-9 are mainly tetrahedrally coordinated even after calcination at 823 K.
