Synthesis of Different Morphological Nanostructures of Titanium Dioxide and to study their Photocatalytic Applications

Abstract

Nanoscience encompasses a wide range of applications and is the most advancing field these days. The small size range i.e, (10-9) of these particles allows them to have efficient surface area and thus providing good catalytic properties. Several methods have been introduced for nanoparticle synthesis and have been industrially employed. Titania nanoparticles being an efficient semiconductor with low recombination rate have been widely studied. Its photocatalytic activity has been reported to be very high. The present work demonstrates the synthesis of various morphologies of titania nanoparticles and its characterization along with its photodegradation properties. Its catalytic activity has been studied in the biodiesel synthesis. The degradation profile of salicylic acid using TiO2 nanoparticles has been studied and the microwave synthesized titania nanoparticles proved to be excellent catalyst as compared to the conventionally synthesized and commercially available counterparts.
