This paper describes the synthesis and performance of Pd/ p ‐TiO 2 ‐MWCNTs for alcohol electrooxidation. Regulation of the steric repulsive forces of polyvinylpyrrolidone was used to achieve even dispersion of Pd nanoparticles over the TiO 2 surfaces. The order of the electroactivities of the Pd/ p ‐TiO 2 MWCNTs in alcohol oxidation was ethanol>ethylene glycol>methanol. The order of the stabilities of alcohol oxidation by Pd/ p ‐TiO 2 MWCNTs was ethylene glycol>ethanol>methanol. Electroimpedance spectroscopy showed that at a potential of −0.1 V, the Pd/ p ‐TiO 2 MWCNTs had good tolerance of adsorbed CO in ethylene glycol oxidation, and at −0.2 V, the Pd/ p ‐TiO 2 MWCNTs had good adsorbed CO tolerance in methanol oxidation.
