Catalytic Processes in Materials Science

Vanadium silicates with the ZSM-48 structure have been synthesized hydrothermally. The maximum incorporation achieved by this method was 0.8 V atoms/u.c. Different techniques have been used to characterize the location and coordination of V atoms in the zeolite. All these techniques suggest that V atoms are most likely incorporated in the framework in a highly dispersed state. Moreover, these solids have shown to be catalytically active in the hydroxylation of phenol with hydrogen peroxide.
