應用

• Single-Atom palladium engineered cobalt nanocomposite for selective aerobic oxidation of sulfides to sulfoxides.: This study presents a novel approach using a palladium-engineered cobalt nanocomposite that promotes the selective aerobic oxidation of sulfides, with isobutyraldehyde acting as an important reagent in the process, offering potential for more efficient and environmentally friendly chemical synthesis (Ma et al., 2024).
