Effect of Different Shapes of TiO2 Nanoparticles on the Catalytic Photodegradation of Salicylic Acid Under UV Light
Titania of different nanostructures was synthesized by microwave synthesis and the conventional method. The synthesized nanostructures of titanium dioxide were characterized by different optical and morphological techniques. The microwave assisted TiO2 nanoparticles [TiO2 (MW)] depicted higher photocatalytic activity along with degradation properties. Photocatalytic degradation is one of the major applications of TiO2. Higher surface area of TiO2 (MW) and TiO2 (TP) was observed as 123 m2/g and 46 m2/g respectively while the specific surface area of TiO2 P25 is 50 m2/g. TiO2 (MW) shows crystallite size of 8.2 nm which holds good as compared with the size reported. The degradation profile of salicylic acid had shown that TiO2 (MW) proved to be a promising catalyst as compared to conventionally synthesized and commercially available counterparts.
