The reported nanosized phosphor was synthesized by low cost and low-temperature wet chemical method. Phase purity and crystallite size were measured by XRD and HRTEM techniques, and photoluminescence characterization was carried out for its downshifting properties. The XRD pattern reveals that the CdWO4 has a monoclinic structure and it is in good agreement with standard PDF pattern. HRTEM images reveal that the phosphor has nanoflakes and nanogranules structural morphology. The present phosphor CdWO4:Ce3+ shows good downshifting property and converts the broad ultraviolet band (ranging from 220 to 400 nm and peaking at 285 nm) into a visible spectral band extending from 400 to 650 nm and peaking at 474 nm.

The present work describes the preparation of CuMnCe, CuMnCo and CuCeZr catalysts and the characterization techniques applied to gain information about the catalyst structure and activity. Among the catalysts, CuMnCe and CuMnCo were prepared by the co-precipitation method and another catalyst CuCeZr was prepared by the reactive grinding method. In the variety of mixed metal oxide catalysts, CuMnCe was considered to be the most effective for high activity. The addition of ceria in CuMnOx catalyst has also improved the activity and stability due to increasing the meso/macropore volume and surface area after aging treatment. A novel route of reactive calcination (RC) of the precursor was the synthesis of highly active catalyst. The amazing activity of the novel catalysts over the conventional ones (obtained by calcination of the precursors in stagnant air and flowing air) in CO oxidation was associated with the unusual morphology as evidenced by XRD, SEM-EDX, XPS, BET and FTIR characterization. The catalysts obtained by RC of various precursors showed the highest activity for CO oxidation in the following order: CuMnCe > CuCeZr > CuMnCo and the traditional route of calcination also followed the same activity order. Further, the activity order of the catalysts obtained by various calcination conditions was as follows: RC > flowing-air > stagnant-air.</div>","PeriodicalId":100888,"journal":{"name":"Materials Discovery","volume":"10 ","pages":"Pages 1-14"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.md.2018.02.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72111325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
