| Abstract | Carbon nanofibers (CNFs) were grown over highly porous (â ¼1750 m(2)/g-surface area) carbon beads (â ¼0.8 mm), using catalytic chemical vapor deposition (CVD). The carbon beads were produced by the pre-oxidation, carbonization and activation of the phenolic beads that were synthesized using the suspension polymerization. The beads were doped in situ with copper (Cu) during the polymerization reaction. The carbon beads decorated with the CNFs were treated with pyridine to increase the nitrogen (N) contents of the material. The N-enriched CNFs and Cu nanoparticles (NPs)-doped carbon beads (N-Cu-CNF/CBs) were used for the removal of nitric oxide (NO) by reduction. In its dual role, Cu catalyzed the growth of the CNFs during CVD, and also, the reduction reaction. Approximately 86% of NO conversion was achieved for 400 ppm-NO concentration over 1 g of the prepared catalyst at 500 °C. The high catalytic activity was attributed to the combined roles of the Cu NPs, reactive CNFs and N-containing surface functional groups in the material. The prepared carbon bead-supported CNFs in this study are for the first time effectively used as the catalyst for the NO reduction without requiring ammonia or urea. |

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.
