| Abstract | The investigation of photocatalysis by efficient visible-light-active photocatalysts has been of interest in both the science and the engineering fields. The nitrogen (N) doped KAl0.33W1.67O6 (KAW) and KCr0.33W1.67O6 (KCW) are prepared by the solid state method. Urea was used as a nitrogen source. These materials were characterised by thermo gravimetric analysis, powder X-ray diffraction, scanning electron microscopy, energy dispersive spectra, X-ray photoelectron spectroscopy (XPS) and UV–visible diffuse reflectance spectroscopy (UV–vis DRS). Both the N-doped materials crystallised in a cubic lattice with space group Fd3̄m. The XPS analysis of the N-doped KAW (N-doped KCW) show the characteristic peaks belonging to K 2p, Al 2p (Cr 2p), W 4f, O 1s and N 1s along with C 1s. The bandgap energy was deduced from their UV–vis DRS profiles. The photocatalytic degradation of the methylene blue solution was investigated in the presence of these oxides. Compared with their parent materials, nitrogen doped KAW and KCW samples exhibit ∼230 and ∼130% increase, respectively, in visible light-induced photodegradation of methylene blue. |

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.
