Abstract
A new large pore tin-silicate analogue of zeolite ZSM-12 (MTW topology ) with Si/Sn molar ratio > 70 has been synthesized hydrothermally usin g a new template, hexamethylene bis(benzyl dimethyl ammonium hydroxide ). This material exhibits an expansion in unit cell volume (XRD), an I R band at 970 cm(-1) and a charge transfer band at 205 nm in the UV-Vi s region indicating the presence of Si-O-Sn units with Sn4+ centers in T-d configuration. Sn-ZSM-12 catalyzes the oxidation of phenol, m-cre sol and m-xylene using dilute H2O2 as an oxidizing agent.
