Preparation of TiO2/SAPO-5 Composite Zeolite and its Photocatalytic Properties for the Degradation of Phenol
Abstract Microporous SAPO-5 with an AFI topology has been synthesized by hydrothermal method; using this material, TiO2/SAPO-5 composite zeolites were prepared using sol-gel technique. The structures of SAPO-5 molecular sieves and TiO2/SAPO-5 composite zeolites were characterized by several analytical techniques. XRD patterns show the high crystallinity and purity of SAPO-5 molecular sieves. The small particle size (500-600 nm) and the large specific surface area have been analyzed by SEM and BET. The photocatalytic activity of TiO2/SAPO-5 composite zeolite was evaluated by photocatalytic degradation of phenol as model reaction. TiO2/SAPO-5 exhibits a higher activity for the degradation of phenol in comparison with pure TiO2.
期刊介绍：
The Journal of advanced oxidation technologies (AOTs) has been providing an international forum that accepts papers describing basic research and practical applications of these technologies. The Journal has been publishing articles in the form of critical reviews and research papers focused on the science and engineering of AOTs for water, air and soil treatment. Due to the enormous progress in the applications of various chemical and bio-oxidation and reduction processes, the scope of the Journal is now expanded to include submission in these areas so that high quality submission from industry would also be considered for publication. Specifically, the Journal is soliciting submission in the following areas (alphabetical order): -Advanced Oxidation Nanotechnologies -Bio-Oxidation and Reduction Processes -Catalytic Oxidation -Chemical Oxidation and Reduction Processes -Electrochemical Oxidation -Electrohydraulic Discharge, Cavitation & Sonolysis -Electron Beam & Gamma Irradiation -New Photocatalytic Materials and processes -Non-Thermal Plasma -Ozone-based AOTs -Photochemical Degradation Processes -Sub- and Supercritical Water Oxidation -TiO2 Photocatalytic Redox Processes -UV- and Solar Light-based AOTs -Water-Energy (and Food) Nexus of AOTs
