Catalytic Oxidation of Alcohols over a Nitrogen- and Sulfur-Doped Graphitic Carbon Dot-Modified Magnetic Nanocomposite

A novel and unique nitrogen- and sulfur-doped graphitic carbon dot (g-CSNCD)-modified magnetic nanocomposite was synthesized through a quasi-chemical vapor deposition method using urea and sulfanilic acid. The abovementioned nanocomposite was then fully characterized. The resulting Fe3O4/g-CSNCDs catalyst served as a potent catalyst for promoting alcohol oxidation in a very selective manner. This study investigated the effect of carbonation of reagents and magnetic nanoparticles on catalytic performance by synthesizing a few controller catalysts. These results confirmed g-CSNCD as effective support. Furthermore, the modification of g-CSNCDs with Fe3O4 nanoparticles was more effective than incorporating them into the catalyst’s framework. Notably, Fe3O4 nanoparticles had no effect on the reaction process and increasing catalytic activity. Additionally, not only can Fe3O4/g-CSNCDs catalyze this reaction but it can also demonstrate respectable recyclability and be magnetically recovered and effectively reused 10 successive times.
