| Abstract: | We have synthesized titanium silicate analogs of VPI-8 zeolite with a broad range of ratios of Si and Ti atoms. We have shown that introduction of titanium into the zeolite lattice is accompanied by an increase in the unit cell parameter from 13.05  to 14.85 , and also an increase in the sorption capacity and a decrease in the characteristic methanol adsorption energy. X-ray phase analysis, IR and UV spectroscopy have confirmed the isomorphic incorporation of Ti in a tetrahedral environment into the structure of VPI-8 zeolite, up to Ti/(Si+Ti) = 0.05. |
