Plasma and electron beam irradiation induced transformation of V-modified MCM-41 to MFI-zeolite
Solid state structural and morphological transformation of the highly ordered mesoporous VMCM- 41 to MFI zeolite with the assistance of plasma and electron beam irradiation was for the first time and in a haphazard way discovered. The preparation procedure has been correlated with this new phenomenon. It is illustrated that the structural transformation is highly dependent on the formation of the silica anions. Both plasma and SEM electron beam irradiation can induce the transformation while electron beam irradiation can accelerate the transformation from V-MCM-41 to MFI-zeolite.
