【 摘 要 】

Aluminophosphate sieves with AFI structure substituted by Ti (denominated TAPO-5) have been synthesized hydrothermally. These materials were characterized by X-ray diffraction (XRD), chemical analysis (ICP), scanning electronic microscopy (SEM), ultraviolet diffuse reflectance spectroscopy (DRS-UV) and thermogravimetric analysis (TGA). XRD results showed the materials have good TAPO-5 crystallinity, although DRS-UV spectra indicated anatase phase as contamination. TGA analysis showed mass loss in the range of high temperatures, which can be attributed to protonated template decomposition. This indicates the existence of structural charge as a consequence of Ti incorporation into AFI structure
