Synthesis of structured filamentous zeolite materials via ZSM-5 coating of glass fiber supports

Structured filamentous zeolitic materials were prepd. by depositing ZSM-5 coatings on glass fiber supports. A homogeneous coverage of the support filaments was obtained by prepg. MFI crystals in F-contg. media at neutral pH. The samples were characterized by BET, XRD and SEM. The gas-phase partial oxidn. of benzene by N2O to phenol was investigated as a function of the chem. compn. of the support and the ZSM-5 synthesis procedure. The fluorinated zeolitic materials demonstrated the highest activity (>20% benzene conversion) with 97% selectivity to phenol. [on SciFinder (R)]
