Structural and textural features of TiO2/SAPO-34 nanocomposite prepared by the sol–gel method

摘要: This paper focuses on the synthesis of nanocomposite materials, TiO2/SAPO-34, using sol–gel method, which involves preparing a mixture between as-synthesized or calcined SAPO-34 zeolite and TiO2 gel under hydrothermal crystallization then calcining it at 400 °C for formation anatase phase. The structural textural features obtained materials were determined by various physico-chemical techniques such as thermogravimetric analysis, X-ray diffraction, scanning electronic microscopy, nitrogen sorption 77 K, energy dispersive analysis ultraviolet–visible spectrometry. DRX results showed that calcination led to collapse original framework zeolite, but formed in nano-spherical morphology; however, use supports provides phase after calcination. photocatalytic properties SAPO-34/TiO2 TiO2-type tested removal methylene blue (MB) dye.
