| Abstract | In the present study, synthesis of titania (titanium dioxide, TiO2) nanoparticles, which show light absorption characteristics in the ultraviolet region, was successfully achieved in the CTAB micelle nanoreactors at room temperature. The shape (or surface morphology), size, elemental composition, crystal structure, and optical properties of these particles were characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and ultraviolet-visible absorption (UV-Vis) spectroscopy. Besides, our proposed method allowed for the successful preparation of highly crystalline and well-dispersed anatase titania nanoparticles with a phase-pure. Evaluation of titania nanoparticles' photocatalytic activity was performed through degrading the methylene blue (MB) dye under ultraviolet light irradiation. Compared to the commercial P25 TiO2 powder, this result is indicative of a high photocatalytic MB dye degradation activity. Also, the effect of the amount of TiO2 nanoparticles in the MB dye degradation has been investigated in detail. Finally, the stability of photocatalytic activity of those nanoparticles has been evaluated. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
