| Popis: | Single phase, crystalline NaFeTiO4 with tunnel structure is prepared by a solid state method and explored as a novel photocatalyst for the first time. Structural, optical and morphological properties of NaFeTiO4 are investigated by various characterization techniques such as X-ray diffraction (XRD), scanning & transmission electron microscopy (SEM & TEM), Energy dispersive X-ray spectroscopy (EDS), N2 adsorption-desorption study (BET), UV-vis, X-ray photoelectron, X-ray absorption (UV-vis DRS, XPS and XANES) and photoluminescence (PL) spectroscopy. The interfacial charge transfer ability of the prepared n-type NaFeTiO4 was also investigated by transient photocurrent response and electrochemical impedence spectroscopy which proved to be an efficient tool for better understanding of electronic properties of NaFeTiO4. The photocatalytic efficiency of NaFeTiO4 is evaluated for decomposition of methylene blue (MB) and Rhodamine B (RhB) dyes as well as for H2 evolution through water splitting reaction under visible light. NaFeTiO4 exhibits efficient charge separation properties, excellent photocatalytic activities and reusability. |
