| Abstract | Three samples of modified HZSM-5 zeolite with tin and copper were prepared by ion exchange and coprecipitation under basic conditions. The catalytic activity of prepared catalysts was tested in CO and methane combustion after pretreatments done at 873, 1088 and 1273 K. The XRD analysis and TG-DTA were used to interpret thermal stability of catalysts. Introduction of tin as the third element to well-known copper-overloaded ZSM-5 combustion catalysts improves their thermal stability. It was found that CO combustion is independent of the zeolite structure and probably adjacent sites are necessary to activate carbon monoxide and oxygen in the vicinity. Contrarily, non-dehydroxylated zeolite is indispensable as an active element together with copper or tin to catalyze methane combustion. |

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.
