Small-angle X-ray scattering spectra and nitrogen physisorption results confirm the formation of the KIT-5 structure. The incorporation of Nb and its coordination were confirmed by techniques such as elemental analysis, diffuse reflectance UV-Vis, Raman, HR-SEM and NH3-TPD. When tested as epoxidation catalyst for styrene with H2O2, Nb-KIT-5 mainlyyielded (1,2-dimethoxyethyl) benzene with methanol as solvent. It also showed better catalytic activity compared to other mesostructured catalysts such as Nb-KIT-6 and Nb-SBA-15.
