| Abstract | Because of their excellent properties, metal-organic frameworks (MOFs) are considered as ideal materials for the development of visible-light photocatalyst. Particularly, although increasing research interests have been put on MOF based photocatalysts, the MOF supported Ag2CO3 as photocatalyst has not been reported in the field of water treatment. In this study, a zirconium based MOF, UiO-66, was incorporated with Ag2CO3 through a convenient solution method and used for visible-light prompted dye degradation. Compared to the mixture of pristine UiO-66 and Ag2CO3, the developed Ag2CO3/UiO-66 composite exhibited enhanced photocatalytic activity to the degradation of rhodamine B (RhB) under visible-light irradiation. It was supposed that the participation of UiO-66 during the synthesis of Ag2CO3 was crucial for such improvement. In addition, the Ag2CO3/UiO-66 composite demonstrated good structural stability after the degradation experiment, and most of its photocatalytic activity was still preserved after the recycle test. Moreover, the photocatalytic mechanism of the Ag2CO3/UiO-66 composite was investigated and a possible pathway of RhB degradation was also proposed. |

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.
