Description
Summary:Titanium oxide (TiO2) nanoparticles have been widely used and researched in recent years due to their wide application in several areas such as solar cells, catalysis and their chemical, non-toxic and electrical properties. Thus, this work aimed to study the catalytic potential of these nanomaterials through the oxidation of benzyl alcohol, for which TiO2 nanoparticles synthesized by the hydrothermal method and decorated with gold nanoparticles obtained by the Turkevich method (TiO2/Au) were used. The catalyst proved to be active for the catalysis of benzyl alcohol oxidation, with a yield of about 73% for the TiO2/Au catalyst and 1.4% for the TiO2 catalyst. Additionally, it was observed that the catalyst was selective, since the GC-MS and FTIR spectra showed only benzaldehyde as the final reaction product. The selective oxidation of alcohols is one of the most significant transformations in organic chemistry, as it is essential for the production of industrial intermediates.
