| Abstract
| - A novel microporous titanosilicate JLU-1 (JiLin University number-1) has been successfullysynthesized in a SiO2−TiO2−Na2O−H2O−(TMA)2O system. It is found that the JLU-1 samplerequires a relatively low alkalinity and appropriate titanium content. The products areindexed as triclinic, a = 13.043(6) Å, b = 12.538(3) Å, c = 17.022(6) Å, α = 79.05°, β =115.00°, γ = 84.81°. The samples have been characterized by powder X-ray diffraction (XRD),29Si magic-angle spinning (MAS) NMR, scanning electron microscopy (SEM), high-resolutiontransmission electron microscopy (HREM), infrared spectroscopy (IR), differential thermal−thermogravimetric analysis (DT-TGA), and adsorption measurements. Factors such as theinitial TiO2/SiO2, Na2O/SiO2, and TMABr/SiO2 molar ratios, crystallization temperature, andcations which dominate the hydrothermal synthesis of the product are discussed.
