The oxidation of veratryl alcohol can produce veratryl aldehyde or veratryl acid, which are industrially important chemicals widely used in the food and pharmaceutical industries. Gold nanoparticles (AuNPs) functionalized with graphene quantum dots (GQDs) have shown high activity and selectivity as a catalyst for veratryl alcohol oxidation. However, the AuNP/GQD catalyst has excellent dispersibility in aqueous solutions, which makes it difficult to recycle all the catalyst after reaction. In this work, AuNP/GQD catalysts were further immobilized onto a silicon dioxide support by different methods, including physical adsorption, one-pot synthesis, and hydrothermal synthesis to produce AuNP/GQD/SiO2 composites. Extensive characterization of the microstructure, crystallinity, chemical structure, and catalytic performance of the catalysts was performed to evaluate the processing methods. It was demonstrated that the obtained composites are suitable heterogeneous catalysts for the oxidation of veratryl alcohol. |
