Selective Oxidation of Benzyl Alcohol to Benzaldehyde under Solvent Free Aerobic Oxidation Condition Using Pd-Supported CeO2 Catalyst
In this research, the homogenous PdNPs were developed with varying weight percentages (1 to 4 wt %) on the CeO2 support using a simple impregnation process with a mean size of 5 nm. Furthermore, homogenous PdNPs were examined for the selective oxidation of benzyl alcohol (BA) to benzaldehyde (BZA) in a solvent-free oxidation technique. The developed Pd/CeO2 heterogeneous nanocatalysts were thoroughly studied utilizing various techniques such as P-XRD, TEM, and XPS analysis. Among various Pd loadings, 3 wt % (3Pd/CeO2) catalysts exhibit enhanced catalytic activity for the BA to BZA oxidation process, with 9.5 times greater BA conversion than bare CeO2. Additionally, experiments were conducted to determine the effect of temperature, catalyst weight, reaction time, and catalyst recyclability. The highest benzyl alcohol conversion (95%), benzaldehyde selectivity (99%) and benzaldehyde yield (94%) achieved for 3Pd/CeO2. The 3Pd/CeO2 catalyst not only exhibited superior catalytic activity, but also showed stable activity during recyclability.
期刊介绍:
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
