Nitrogen and phosphorus co-doped Vulcan XC-72 carbon support (C-NP-800) was prepared by cal-cining under 800？C. Nitrogen and phosphorus co-doped carbon supported Pd catalyst (Pd/C-NP-800) was synthesized by an improved liquid reduction method. The catalytic activity of the formic acid oxidation was investigated by physical characterization including XRD, XPS, EDS, TEM and Raman and electrochemical method of cyclic voltammetry and chronoamperometry. The results showed that the carbon supported palladium catalyst doped with nitrogen and phosphorus had smaller particle size of Pd, higher activity and stability for formic acid electrocatalytic oxidation, and stronger resistance to CO poisoning.
