| Abstract | Multifunctional nanocomposites (GO-TiO2-Ag) integrating 2D GO sheets, 1D TiO2 nanorods and 0D Ag nanoparticles were synthesized via a facile two-phase method and characterized by various analytical techniques including TEM, EDS and XRD. The GO-TiO2-Ag nanocomposites demonstrate remarkably enhanced photocatalytic activities in degrading AO 7 and phenol under solar irradiation compared with GO-TiO2 and GO-Ag. They also exhibit excellent intrinsic antibacterial activity toward Escherichia coli, as well as significantly enhanced photo-biocidal capability over GO-TiO2 and GO-Ag. Through systematically investigating the influence of Ag content in the nanocomposites for their photocatalytic activities, it indicates that the optimal Ag content in the GO-TiO2-Ag nanocomposites varies for dye degradation and for phenol/bacterial degradation with different mechanisms. The superior photocatalytic activities under solar irradiation and the easy recovery make the GO-TiO2-Ag nanocomposites a good promising candidate for water purification. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
