Heterogeneous photocatalysis is a progressive oxidation technique. An alluring process for synthesizing organic compounds is the selective oxidation of benzyl alcohol into benzaldehyde, a valuable intermediate in various chemical syntheses. This transformation not only showcases the efficiency of photocatalytic processes but also highlights the significance of optimizing reaction conditions and catalyst characteristics to enhance reaction rates. This paper reviewed the influence of various operating and morphological variables (e.g., solvent, temperature, and light intensity) on the reaction rate. The solvothermal synthesis of TiO2 significantly impacted the rate constant, and photo-deposition was a viable alternative when both catalyst and support were available. Among crystalline TiO2 nanostructures (e.g., nanowires, nanotubes, nanofibers, nanosheets, and hollow nanospheres), the hollow structure nanosphere enhanced photo-catalytic activity. Increasing light intensity and temperature enhanced the reaction rate. Higher light intensity and temperature caused better rate constant. Among reviewed catalysts, C-ZnInS4, ZnInS4, Pt-TiO2, RuO2/TiO2NB, 0.95Ru/3DOM BiVO4-Ar-300, Pt/Bi2MoO6-glycerol, Ni-OTiO2, W10O4−32, WO3(7.6)/TiO2, TiO1.966N0.034 and Bi2WO6 with the rate constant of 75.0, 53.75, 57, 46.0, 38.0, 34.0, 33.25, 29.6, 28.0, 27.0 and 22.25 gcat-1 h-1 respectively were selected as a suitable catalyst for alcohols oxidation to aldehyde. Notably, TiO1.966N0.034 and ZnIn2S4 achieved 100% conversion in 4 and 2 hours, respectively, with a high selectivity of >99%, demonstrating excellent photocatalytic activity.

An alluring process for synthesizing organic compounds is the selective oxidation of benzyl alcohol into benzaldehyde, a valuable intermediate in various chemical syntheses. This transformation not only showcases the efficiency of photocatalytic processes but also highlights the significance of optimizing reaction conditions and catalyst characteristics to enhance reaction rates. This paper reviewed the influence of various operating and morphological variables (e.g., solvent, temperature, and light intensity) on the reaction rate. The solvothermal synthesis of TiO2 significantly impacted the rate constant, and photo-deposition was a viable alternative when both catalyst and support were available. Among crystalline TiO2 nanostructures (e.g., nanowires, nanotubes, nanofibers, nanosheets, and hollow nanospheres), the hollow structure nanosphere enhanced photo-catalytic activity. Increasing light intensity and temperature enhanced the reaction rate. Higher light intensity and temperature caused better rate constant. Among reviewed catalysts, C-ZnInS4, ZnInS4, Pt-TiO2, RuO2/TiO2NB, 0.95Ru/3DOM BiVO4-Ar-300, Pt/Bi2MoO6-glycerol, Ni-OTiO2, W10O4−32, WO3(7.6)/TiO2, TiO1.966N0.034 and Bi2WO6 with the rate constant of 75.0, 53.75, 57, 46.0, 38.0, 34.0, 33.25, 29.6, 28.0, 27.0 and 22.25 gcat-1 h-1 respectively were selected as a suitable catalyst for alcohols oxidation to aldehyde. Notably, TiO1.966N0.034 and ZnIn2S4 achieved 100% conversion in 4 and 2 hours, respectively, with a high selectivity of >99%, demonstrating excellent photocatalytic activity. }, year = {2024} }

An alluring process for synthesizing organic compounds is the selective oxidation of benzyl alcohol into benzaldehyde, a valuable intermediate in various chemical syntheses. This transformation not only showcases the efficiency of photocatalytic processes but also highlights the significance of optimizing reaction conditions and catalyst characteristics to enhance reaction rates. This paper reviewed the influence of various operating and morphological variables (e.g., solvent, temperature, and light intensity) on the reaction rate. The solvothermal synthesis of TiO2 significantly impacted the rate constant, and photo-deposition was a viable alternative when both catalyst and support were available. Among crystalline TiO2 nanostructures (e.g., nanowires, nanotubes, nanofibers, nanosheets, and hollow nanospheres), the hollow structure nanosphere enhanced photo-catalytic activity. Increasing light intensity and temperature enhanced the reaction rate. Higher light intensity and temperature caused better rate constant.
