Synthesis and characterization of zeolite FSM-16 and TiO2/FSM-16

Zeolite FSM-16 was synthesized by reconstruction of layered silicate in the presence of organic surfactant. With partial replacement of Ti3+ with orga nic cations, TiO2 nano-structured particles were simultaneously built in th e channel of the zeolite as the framework of the zeolite was formed. XRD, I R and Raman spectroscopic characterizations indicate that SiO4 tetrahedron may be distorted and transferred from Q(3) to Q(2) form due to the pucker a nd reconstruction of the layered structure. The formation of TiO2 nanostruc tured particles had no influence on the formation of zeolite framework, how ever, the interaction obviously occurred between TiO2 nano-structured parti cles and zeolite framework.
