Palladium nanoparticles (Pd‐NPs)/polyaniline (PAni)/titanium (Ti) catalysts were prepared using electroless deposition of Pd‐NPs on PAni matrixes coated on Ti substrate. PAni/Ti electrodes were synthesized by electro‐polymerization of aniline on Ti. The morphology of Pd‐NPs on PAni/Ti electrodes were characterized by scanning electron microscopy technique and results indicated that Pd‐NPs were uniformly dispersed on the surface of PAni film. The electro‐catalytic properties of Pd‐NPs/PAni/Ti catalysts toward oxidation of hydrazine were investigated by different electrochemical methods and results showed that Pd‐NPs/PAni/Ti catalysts have high electrochemical activity. In addition, the mechanism of hydrazine electrochemical oxidation catalyzed by Pd‐NPs/PAni/Ti was investigated. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
