Preparation of Large-Size, Superparamagnetic, and Highly Magnetic Fe(3)O(4)@PDA Core–Shell Submicrosphere-Supported Nano-Palladium Catalyst and Its Application to Aldehyde Preparation through Oxidative Dehydrogenation of Benzyl Alcohols

Large-size, superparamagnetic, and highly magnetic Fe(3)O(4)@PDA core–shell submicrosphere-supported nano-palladium catalysts were prepared in this study. Dopamine was encapsulated on the surface of Fe(3)O(4) particles via self-polymerization and then protonated to positively charge the microspheres...

description Large-size, superparamagnetic, and highly magnetic Fe(3)O(4)@PDA core–shell submicrosphere-supported nano-palladium catalysts were prepared in this study. Dopamine was encapsulated on the surface of Fe(3)O(4) particles via self-polymerization and then protonated to positively charge the microspheres. PdCl(4)(2−) was dispersed on the surface of the microspheres by positive and negative charge attraction and then reduced to nano-palladium. With air as oxidant, the catalyst can successfully catalyze the dehydrogenation of benzyl alcohols to produce the corresponding aldehydes at 120 °C.
