| Abstract | Using plant materials as templates is a convenient and low-cost route to prepare solid base catalysts with high specific surface area. In this study, a series of biomorphic calcium oxide/carbon catalysts have been prepared via an in situ transformation technique using rice grains as a template and carbon precursor. The resulting CaO/carbon materials are spindly shaped catalysts and show a high specific surface area and strong basicity. In the methylation of cyclopentadiene, these CaO/carbon materials exhibit a higher catalytic performance than MgO/carbon materials and CaO prepared by directly calcining the CaO precursor. Moreover, the regeneration of deactivated catalyst is studied, and steam or CO2 treatment at high temperature is found to be very effective for this carbon supported catalyst, and can even promote the catalytic activity. A possible mechanism for the deactivation and regeneration of the CaO/carbon materials has been proposed. |

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.
