With partial replacement of Ti 3+ with organic cations, TiO 2 nano structured particles were simultaneously built in the channel of the zeolite as the framework of the zeolite was formed. XRD, IR and Raman spectroscopic characterizations indicate that SiO 4 tetrahedron may be distorted and transferred from Q 3 to Q 2 form due to the pucker and reconstruction of the layered structure.

文摘Zeolite FSM 16 was synthesized by reconstruction of layered silicate in the presence of organic surfactant. With partial replacement of Ti 3+ with organic cations, TiO 2 nano structured particles were simultaneously built in the channel of the zeolite as the framework of the zeolite was formed. XRD, IR and Raman spectroscopic characterizations indicate that SiO 4 tetrahedron may be distorted and transferred from Q 3 to Q 2 form due to the pucker and reconstruction of the layered structure. The formation of TiO 2 nano structured particles had no influence on the formation of zeolite framework, however, the interaction obviously occurred between TiO 2 nano structured particles and zeolite framework.
