Visible‐Light‐Enhanced Photocatalytic Activity of Totally Inorganic Halide‐Based Perovskite

Abstract: The removal of contaminants is an interesting topic in environmental research and for society nowadays. In this sense, perovskite materials have proven to be amazing photocatalysts. In this study, CsSnBr3 perovskite was synthesized and characterized using techniques such as x‐ray diffraction, Raman spectroscopy, x‐ray photoelectron spectroscopy and UV‐vis spectroscopy. A mixture of cubic and tetragonal crystalline phases was found in the sample, and XPS revealed the presence of two oxidation states for Sn, and… Show more

“…In 2018, Reyes-Pérez et al successfully synthesized CsSnBr 3 HPs, which were a more environmentally friendly alternative than their Pb-containing counterparts, and used them for the removal of crystal violet dye. 84 Both cubic and tetragonal phases were detected in the X-ray diffraction (XRD) patterns of these HPs, and X-ray photoelectron spectroscopy analysis revealed the presence of two oxidation states of Sn: 47.8% Sn 2+ and 52.2% Sn 4+ . These HPs also exhibited good light absorption in the 400-700 nm visible spectral region, which represented a great advantage for their photocatalytic applications.…”

“…Recently, the impressive response achieved through MHPs has inspired applications well beyond those previously mentioned. In addition to the various well-known applications, MHPs have been utilized as remarkably efficient photocatalysts for numerous light-driven reactions, including wastewater treatments [179,180]. The first results in photocatalytic wastewater treatment belong to Aamir et al [181], who reported the preparation of new hydroxyl ammonium lead halide perovskites, OHNH 3 PbI 2 Cl and OHNH 3 PbCl 3 , which showed suitable stability in an aqueous medium and visible light activity in the photocatalytic degradation of yellow dye under ambient conditions.…”

“…Environmentally friendly alternative approaches, with respect to the commonly employed lead-based MHPs, have been successfully proposed by Reyes-Pérez et al [179], by employing CsSnBr 3 in crystal violet photodegradation under visible light irradiation. A similar approach was employed for the degradation of methylene blue and methyl orange by nanostructures of TlCdI 3 , synthesized by a new, efficient and quick mechanical method [186].…”
