Abstract:
In this framework study, an attempt was made to synthesize, characterize, and develop some applications of nano AlF۳ (nAF) by sol-gel method. Meanwhile, precursor gel preparation and the interaction on the nano-sized area have been studied. By nAF the ZnAl۲O۳/AlF۳ (ZA) nanocomposite has been successfully prepared and Structural, morphological and thermal characterization has been done using by FT-IR, XRD, SEM, TG-DTG, and HRTEM techniques. This nanocomposite was used for the removal of Congo red dye. For this purpose, the morphology and the structure of crystals has been changed by modification on precursor gel. When precursor gel has been changed from ۴ to ۹ h, the size of crystals decreased to ۱۵-۲۰ nanometers. The results showed that ZA have been efficiency for photocatalysts in decolorization of Congo red.
