Novel Routes For Heterogenizing Gold Nanoparticles For Catalytic Oxidation Using Molecular Oxygen

Abstract

Two different methods for preparing gold catalysts have been investigated in this project: deposition precipitation with NaOH (DP NaOH) and urea (DP urea) methods. On a collection of metal oxide materials as supports, gold has been deposited as nanoparticles. Gold particles less than 5 nm in diameter were obtained based on TEM measurements. Various assisted Au catalysts prepared by deposition precipitation with NaOH show unmatched catalytic efficiency for selective nanoparticles. In contrast to the other Au catalysts, alcohol oxidation. Gas chromatography analyzed both of the reactions. The product shows that in the presence of supported nanoparticle Au catalyst provided by the DP NaOH process, the selective benzyl alcohol oxidation to benzaldehyde in air could be completed with elevated conversion and selectivity at 403 K.
