| Abstract | Vanadium phosphate (VPO) materials with high specific surface area prepared via a eutectic mixture as solvent and template with different lengths of time, i.e. 24, 72 and 144 h, were investigated in the oxidation of benzyl alcohol. The X-ray diffraction result indicated the initial VPO precursor was an amorphous phase due to the stronger incorporation of eutectic mixture. On subsequent reflux duration of 72 h, the precursor was composed of a crystallised VOHPO4·H2O phase. On further reflux duration of 144 h, the incorporated eutectic mixture gradually was leached out and the precursor became more crystalline. Interestingly the N2 adsorption–desorption measurements Brunauer–Emmett–Teller studies showed that the VPO precursor incorporated eutectic mixture was mesostructured and the specific surface area first increased then decreased with increasing the reflux duration time. The growth process of the VPO nanostructures formed in a eutectic mixture with different lengths of time was investigated by scanning electron microscopic analysis. The influence of calcination temperature and lengths of reflux duration on the activity and selectivity of the VPO catalyst was studied and discussed. |

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.
