| Abstract | In this work, Ag nanoparticles (AgNPs) with average sizes of 20 nm were well-dispersed on the surfaces of magnetic carbon-coated Fe3O4 (Fe3O4@C) microparticles through a simple in situ growth process. The catalytic efficiency of the as-prepared AgNPs-decorated Fe3O4@C particles was evaluated using a model reaction based on the reduction of 4-nitrophenol (4-NP) by an excess of NaBH4. The kinetic data of the reduction reaction could be explained by the assumption of a pseudo-first-order reaction with regard to 4-NP. Also the particles are catalytically more active due to their extremely high-density AgNPs immobilised on the surfaces of Fe3O4@C particles. Significantly, the Fe3O4@C@Ag catalysts can be easily separated from the reaction media by applying an external magnet, and can be reused for several cycles. |

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.
