Selection of suitable method for the synthesis of Vanadium oxide/Titania (V2O5/TiO2) catalyst on different supports and its characterizations
The development of catalyst is making the interest of researchers towards its synthesis. Â Vanadium pentoxide/titanium dioxide catalyst is the most important catalyst used in many industrial reactions like Â Â oxidations of aromatics, alkanes, and the catalytic reduction of NOx etc.Â Various methods for synthesis of vanadium pentoxide/titanium dioxide are available employing impregnation, adsorption from solution, chemical vapor deposition, co-precipitation, and the Sol-Gel method have been studied. The detail study of these synthesis techniques reveals that Sol-Gel method is most suitable method for synthesis of V2O5/TiO2 catalyst. This method is nontoxic, environmental friendly, economical and simplest experimental setup. It has been studied that the properties of V2O5/TiO2 catalyst depend upon its preparation procedure. V2O5/TiO2 has been reviewed to study the redox properties, structural analysis, absorption & emission, elemental information, paramagnetic behavior and surface area of catalyst by using temperature programmed reduction, solid state NMR, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, electron spin resonance and Brunauer, Emmett and Teller BET techniques respectively. This review focuses on V2O5/TiO2 synthesis and its characterizations.
