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.
