Abstract | TiO2-SnO2 solid solution supports was prepared by coprecipitation method with different SnO2 content(molar fraction)and calcination temperature and V2O5 was loaded on the supports to obtain V2O5/ TiO1-xSnxO2 catalysts by wet-impregnation method. The support and catalyst were characterized by X-ray diffraction (XRD) and BET and their catalytic performances for the selective catalytic reduction of NOX with NH3 were investigated on in a quartz tubular fixed-bed microreactor to compare preparation methods of solid solution on the catalytic activity of De-NOx. The study indicates that different ratios of SnO2 to TiO2 can form continuous solid solution which has rutile crystal structure. The particle size of the solid solution is smaller than that of pure TiO2 or pure SnO2.The change of the surface area of the SnO2-TiO2 solid solution with the SnO2 or TiO2 content is a volcano shape curve and the solid solution with 50% SnO2 content has largest BET surface area and highest De-NOx activity. Rutile crystal structure begins to appear in the SnO2-TiO2 solid solution calcined at 450℃ and replaces anatase phase more as calcination temperature rises and no anatase crystal structure can be detected at 700℃ according to XRD result. The BET surface area of solid solution and catalysts declines with higher calcination temperature, either. De-NOx activity V2O5/ TiO1-xSnxO2 shows the same trend. V2O5/ TiO1-xSnxO2 catalyst calcined at 450 ℃ comprises both anatase and rutile phase of TiO2,showing higher thermal stability,larger surface area and stronger De-NOx activity, while 1% V2O5 loading supported on TiO0.5Sn0.5O2 solid solution is highly active for NO removal. |

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.
