| Abstract | A three-dimensional TiO2/Bi2WO6 hierarchical heterostructure was successfully prepared by a simple and practical liquid phase method. The as-synthesised nanostructure consisted of TiO2 nanoparticles growing on the surface of flower-like Bi2WO6 microspheres. The UV–vis diffuse reflectance spectra indicated that the TiO2/Bi2WO6 composites have a significantly enhanced optical absorption in the visible light region and red-shift phenomenon compared with that of pure Bi2WO6 microspheres. The photocatalytic activity of the TiO2/Bi2WO6 composites increases first and then decreases with increasing loading content of TiO2 under 500 W Xe lamp light irradiation. The composite coated with 3 ml content tetrabutyl titanate showed the highest photocatalytic activity compared with that of the other samples in the decomposition of Rhodamine B in water which is a typical model pollutant. The improved light harvesting ability and efficient separation of photo-generated electron and hole pairs could be responsible for the improved photocatalytic performance. |

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.
