Iron oxide/Pd hybrid nanostructures with controllable Pd loading from 0.05 to 1.0 (calculated as Pd/Fe molar ratio) have been synthesized by chemical reduction of Pd2+ on iron oxide particles. The combination of iron oxide and Pd exhibits enhanced peroxidase-like activity and catalytic activity toward reduction of 4-nitrophenol. The catalytic enhancements were found to be dependent on the Pd loading amount as well as the synergistic effect between iron oxide and Pd. These results suggest that iron oxide with unique surface chemical state can be an active supporter and suggest an effective way to design superior hybrid nanostructures for catalytic applications.
