Abstract
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.
