TEM Study of Ti Doped ZSM-5 Zeolite

The hydrothermal treatment of zeolite powder leads to the strong changes in the morphology of zeolite particles. In the particles characterised by homogeneous structure before thermal treatment the formation of holes after thermal treatment was observed. These changes lead to the enrichment of zeolite with titanium that enhance its catalytic activity. The titanium surplus precipitates as small TiO2 anatase particles within the holes
