| Abstract | In this work, a series of porous zinc oxide (ZnO) architectures were prepared by changing the concentration of trisodium citrate by using a green hydrothermal and calcination method, and the photocatalytic performance of the ZnO samples were investigated by using Rhodamine B as degradant under ultraviolet irradiation. The concentration of trisodium citrate had a great influence on the morphology, structure and optical properties of the ZnO samples, which together affected the photocatalytic activity. With the increase of trisodium citrate concentration, the morphology of as-prepared hexagonal wurtzite ZnO changed from flower-like to porous microsphere, and then formed bigger spheres which were more tightly assembled by nanosheets. The higher photocatalytic performance of ZnO microsphere prepared from 1 × 10−3 mol·l−1 trisodium citrate solution was due to the hierarchical pore structure, its better ultraviolet light absorption and higher charge separation. Moreover, the mechanism of the dye photodegradation reaction was 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.
