| Abstract | Well-crystallized square-like bismuth oxychloride (BiOCl) nanoplates were successfully synthesized by a facile and environmentally friendly hydrothermal process in mannitol solution. The product was characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), Raman spectroscopy, UV–vis diffuse reflection spectroscopy (DRS) and nitrogen adsorption. It was found that mannitol played a key role in the formation of square-like BiOCl nanoplates and the possible growth mechanism was also discussed. The photocatalytic activity of prepared BiOCl nanoplates was determined by the degradation of Rhodamine B (RhB) under visible light irradiation. The square-like BiOCl nanoplates exhibited excellent visible-light-driven photocatalytic efficiency, which was much higher than that of commercial BiOCl and TiO2 (anatase). The remarkable visible-light photocatalytic activity was mainly attributed to the synergistic effect of the layered structure and the strong adsorption of RhB dye upon the BiOCl nanoplates, which might allow more efficient transport of the injected electrons. A possible dye-sensitized photocatalytic degradation process (photosensitization pathway) was 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.
