| Abstract | A novel strategy for preventing aggregation, increasing surface area, and maintaining catalytic activity of water-soluble graphene nanosheet (GNS) catalysts is introduced, and use of the synthesized nanocatalyst [GNS (matrix)/metal (catalyst)/metal oxide (spacer)/ceramic (protector)] as recyclable nanocatalysts without loss of performance is demonstrated. Our graphene nanocomposite (GNC) armed with nanoneedles is fabricated by the synthesis of Au on GNS, followed by stepwise synthesis of needle-like IO and SiO2, in order. The distinctive structures of the needle-like layers prevent aggregation and contamination of the GNS catalysts, and allow recycling, both of which enhanced catalytic ability. The research demonstrates the possibility of a safe coating for water-soluble GNS catalysts, which are reactive to ionic species, and their application as nanocatalysts for the chemo-selective transformation of toxic substances. Our sandwich-like GNCs for recyclable nanocatalysts provide a new design concept for reusable GNS catalysts. |

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.
