Synthesis of novel Bi0.5Na0.5Ti0.95 (Ni0.2Fe0.2Sb0.6)0.05O3 perovskite material used as a photocatalyst for methylene blue degradation under sunlight irradiation
In this study, we synthesized a novel ceramic material Bi0.5Na0.5Ti0.95 (Ni0.2Fe0.2Sb0.6)0.05O3 named BNT-NFS via the solid-state route and assessed its efficacy as a photocatalyst for removing methylene blue dye from wastewater. The synthesized samples underwent thorough characterization using thermogravimetric analysis combined differential thermal analysis TGA-TDA, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) analysis, and UV–Visible measurements. TGA-DTA and XRD analyses confirmed the successful formation of BNT-NFS material at 1150 °C, exhibiting a hexagonal phase structure. FTIR analysis revealed an intense band at 421 cm−1, corresponding to metal-oxide vibrations in the BNT-NFS spectrum. SEM observations unveiled a distinct microstructure of BNT-NFS composed of grains of varying sizes. BET analysis indicated that the prepared BNT-NFS powder possessed a significant specific surface area of 261.36 m2/g. Optical and photocatalytic assessments demonstrated that BNF-NFS perovskite is a semiconductor material with a band gap of 2.73 eV, exhibiting satisfactory photocatalytic activity for methylene blue MB dye removal. Notably, the removal efficiency reached 60% after 210 min of exposure to sunlight irradiation. This result is better than that registered for the pristine BNT.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
