A Honeycomb Layered Na2SnO3 as Novel Photocatalyst for Degradation of Rose Bengal Dye

A layered Na2SnO3 with honeycomb structure was synthesized by solid state route using sodium carbonate and tin oxide. The prepared sample was characterized by different physicochemical characterization techniques like X‐ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X‐ray spectroscopy (EDS), X‐ray photoelectron spectroscopy (XPS), ultraviolet visible spectroscopy (UV–vis), photoluminescence spectra (PL), N2 adsorption technique (Brunauer–Emmett–Teller, electrochemical impedance spectroscopy (EIS). The photodegradation of rose bengal dye under UV light was studied. Due to honeycomb structure and high surface area of Na2SnO3, the complete degradation of rose Bengal was observed in 90 min under UV light irradiation. Results of photocatalytic dye degradation reaction demonstrated that Na2SnO3 can be employed as photocatalyst under UV light irradiation. This work involves the solid‐state synthesis and structural characterization of layered Na2SnO3 having honeycomb structure. Na2SnO3 is characterized with different physicochemical characterization tools like XRD, FESEM, EDS, XPS, UV–vis, PL, N2 adsorption, EIS, and so forth. Na2SnO3, was found to effectively degrade rose bengal dye under UV light irradiation.
