| Abstract | The efficient utilization of renewable lignocellulosic biomass has attracted much attention in recent years. One of the most desirable routes for the transformation of cellulose, the main component of lignocellulosic biomass, is to convert cellulose under mild conditions selectively into a value-added chemical or into a platform compound, which can be easily converted to versatile chemicals or fuels in the subsequent step. The activation of cellulose, typically starting by the cleavage of its glycosidic bonds, under mild conditions and the selective formation of a particular molecule are critical challenges. Bifunctional catalysts coupling the acid sites for the activation of the glycosidic bonds via hydrolysis and the metal nanoparticles for the hydrogenation or oxidation of glucose intermediate have shown promising performances for the conversion of cellulose or cellobiose into hexitols or gluconic acid in water under mild conditions. This short review has summarized some recent studies on the development of such bifunctional catalysts or catalytic systems. The following two kinds of bifunctional catalysts or catalytic systems have mainly been discussed: (1) a liquid acid in combination with a supported metal catalyst, (2) solid acid-supported metal nanoparticles. Emphases have been laid on the conversions of cellulose or cellobiose into sorbitol and gluconic acid catalyzed respectively by ruthenium and gold nanoparticles loaded on carbon nanotubes bearing acid sites. |

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.
