“…The high photocatalytic activity of BaSnO 3 under UV light, and the efficiency of electro-photocatalytic ibuprofen of BaSnO 3 under UV increased up to 68 %. [24] Nonetheless, a small activity of BaSnO 3 for the photodegradation of organic dyes is typically reported, being assigned to its high electron-hole recombination rate. This drawback may be overcome by the use of BaSnO 3 /TiO 2 heterostructures.…”

The novel BaSnO 3 /TiO 2 @HNTs photocatalysts were successfully synthesized by co-precipitation peroxide and sol-gel methods. Microstructures, morphologies, compositions, optical and electrochemical properties of the composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), fourier-transform infrared spectroscopy (FT-IR), UV-vis diffuse reflectance spectroscopy (DRS), photoluminescence spectroscopy (PL), Brunauer-Emmett-Teller (BET), electrochemical impedance spectroscopy (EIS) and ion chromatography (IC) methods. The effects of different mass ratios of BaSnO 3 and TiO 2 @HNTs, initial concentration and pH of methylene blue (MB) on the photocatalytic degradation performance of the composites were studied via photodegradation of MB under simulated sunlight irradiation. The characterization results showed that BaSnO 3 /TiO 2 heterojunction and halloysite nanotubes (HNTs) enhanced the electron-hole pairs separation. The BaSnO 3 /TiO 2 @HNTs (BTH-0.6) composites presented the highest specific surface area (67.957 m 2 /g), photocatalytic activity (92 %), and MB (C t = 40 mg/L, pH 7) degradation efficiency (2-4 times that of TiO 2 , BaSnO 3 and BaSnO 3 /TiO 2 ). Furthermore, the capture experiments verified that ⋅OH, h + and ⋅O 2 À were the main active substances during the photo-catalytic reaction, and a possible degradation mechanism was suggested for their photocatalytic degradation in the presence of BaSnO 3 /TiO 2 @HNTs.

“…Increasing attention is now being diverted to mixed valence oxides [80][81][82] and ternary oxides [83][84][85][86][87] as photocatalysts for visible light driven selective photocatalytic conversions. Manikandan et al [88] reported a facile hydrothermal synthesis of mixed-valency tin-oxide (SnO/SnO 2 / Sn 3 O 4 @TiO 2 ) for visible light driven water splitting.…”

With an increase in awareness about the need for green chemistry, there is a shift in focus towards identifying eco-compatible technologies that can improve product yield and eliminate the use or generation of hazardous compounds. An immediate practical example of such an approach is the development of sustainable methods for alcohol oxidation as alternatives to the current processes that are energy intensive and rely on ecotoxic chemicals. In this regard, heterogeneous photocatalysis has been identified as a robust technique to catalyze reactions under benign conditions, which would otherwise require harsh synthesis routes. With the advent of materials sciences and nanotechnology, there has been a tremendous increase in the scope of applicability of photocatalysis in fine chemicals synthesis. Though an attractive choice, much of the fundamental information pertaining to catalyst activity, selectivity and reaction conditions for optimum conversion are still to be investigated for most of these systems. To this end, this review will encompass recent achievements in the selective photocatalytic oxidation of alcohols by harnessing solar radiation as a viable source of energy. The discussion will be arranged based on common types of photocatalysts reported in literature, namely metal oxides (eg, TiO 2 and ZnO, Nb 2 O 5), sulphides (eg, CdS, CuS, and Bi 2 S 3), and carbonaceous photocatalysts (eg, g-C 3 N 4). Several such candidates for photocatalysts will be discussed critically with the aim of providing useful insight into developing selective photocatalysts that can oxidize alcohols via eco-friendly pathways along with high yields.
