| Abstract | UiO-66 amine functionalized was synthesized by solvothermal method. Post-synthetic modification of UiO-66-NH$_{2}$ with piperazine, a known promoter to enhance the chemisorption rate of CO$_{2}$ uptake, was carried out and analyzed to understand its crystalline structure, morphology and porous structure. Results show that piperazine is an effective agent for enhancing the capacity of absorption of CO$_{2}$. This porous product exhibits an improved CO$_{2}$ uptake at pressures up to 3000 kPa via physisorption and chemisorption mechanisms. The CH$_{4}$ adsorption and desorption isotherms on UiO-66, UiO-66-NH$_{2}$ and pip-UiO-66-NH$_{2}$ at temperature of 298.15 K and pressures ranging from 0 to 5000 kPa were carried out. IAS theory for a mixture of 0.05 bar CO$_{2}$, 0.85 bar CH$_{4}$ and 0.1 bar other gas revealed a selectivity factor of 19.09 for CO$_{2}$/CH$_{4}$ from pip-UiO-66-NH$_{2}$. Results show that these materials are effective adsorbents for CO$_{2}$ and CH$_{4}$ uptakes. |

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.
