| Abstract | Platinum–tin (Pt–Sn) nanoalloy catalyst supported on Al2O3 was prepared by carbonylation–impregnation method. The catalyst was characterised by means of nitrogen adsorption–desorption, X-ray diffraction and transmission electron microscope, showing the existence of Pt and Sn as Pt3Sn alloy. The analysis of particle size distribution revealed that Pt–Sn nanoparticles have high dispersion and narrow particle size distribution with an average diameter of 1.7 ± 0.4 nm. Its catalytic performance toward propane dehydrogenation was also investigated. The propane dehydrogenation reaction showed that the as-prepared Pt–Sn/Al2O3 catalyst exhibited good dehydrogenation performance with the conversion of 27.1% and propylene selectivity of 93.3% after reacting 12 h owing to the close interaction between Pt and Sn components. Coke deposition of the used catalyst was characterised by thermogravimetric and differential thermal analysis method, revealing most of the carbon was on the surface of the support, which meant that more active sites to be accessible to maintain catalytic stability. |

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.
