The immobilized catalyst of KIT-N+-PWxOy was stable and robust for the epoxidation. In addition, the active species of PWxOy, the molecular sieve support of KIT-1 and the immobilized catalyst of KIT-N+-PWxOy were characterized by FT-IR, UV-vis, XRD, 31P MAS NMR, SEM, N2 adsorption/desorption, ICP and XPS in detail.
