Poisoning effect diminished on a novel PdHoOx/C catalyst for the electrooxidation of formic acid

A surprisingly high and stable current was observed after the peak current on the PdHoOx/C catalyst indicating the diminished poisoning effect. Moreover, the novel PdHoOx/C catalyst exhibited excellent catalytic activity and stability for formic acid oxidation due to the large electrochemical surface area and electronic effect.
