| Abstract | In this study, gram scale ultrathin (4 nm on average) boron nitride nanosheets (BNNSs) have been prepared through a simple route by using boron oxide, zinc powders and N2H4·2HCl in a stainless steel autoclave at 500 °C. The high thermal stability and high specific surface area (226 m2 g−1) of these BNNSs enable them to be candidates for the high efficiency catalyst support. For example, monodispersed Pt and Au nanoparticles with mean diameters of ∼4.0 and 3.3 nm were successfully loaded on the surfaces of BNNSs, respectively. The Au/BNNSs and Pt/BNNSs would be efficient catalysts in various reactions. It is found that the Pt/BNNSs catalysts towards CO conversion have shown lower full conversion temperature and higher stability. Besides, the gram scale BNNSs might have many other potential applications, such as in polymer composites with high thermal conductivity, electron field emission and the absorbent in gas/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.
