| Abstract | In this research, we studied an easy method to prepare pure cerium oxide nano particle (CeONP), pure zinc oxide nano particle (ZnONP) and Ce/Zn nano composite (Ce/ZnONP) coupled oxide by one pot reaction of cerium and zinc nitrate as precursors in aqueous solution using a Teflon-lined stainless autoclave at 120 °C for 12 h. Model water pollutant Acid Black 4BN as a di-azo textile dye was used to compare the photo-catalytic activity of (CeONP), (ZnONP) and (CeZnONP) deposited on flat-glass surface to overcome the problem of nano catalyst separation from suspension. Thermal, structural and spectral characterization of nano-structures were studied by thermo-gravimetric analysis, X-ray diffraction method, field emission scanning electron microscopy, Fourier transform infrared spectroscopy, energy dispersive X-ray spectroscopy. The elemental analysis using energy dispersive X-ray spectroscopy proved the existence of cerium and zinc in immobilized nano-structures Ce/Zn oxides. The X-ray diffraction result of the composite showed high crystalline cubic cerium oxide and hexagonal wurtzite zinc oxide. The photo-catalytic activity of Ce/Zn nano composite oxide coated on flat-glass surface for degradation dia-azo dye was enhanced compared to their single oxide counterparts. This heterogeneous photo-catalytic degradation of dia-azo dye can be applied as an alternative to suspended oxide powders and over-come drawbacks of filtration of photo-catalysts. This study for the first time showed the potential application of Ce/Zn nano composite for removal of organic pollutant from water. |

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.
