Nano-sized Pt-Ir particle was synthesized by electrodeposition method with carbon fiber paper as the substrate.The morphology,structure and element composition of the electrocatalyst were studied by scanning electron microscope（SEM）,transmission electron microscope（TEM）,X-ray energy spectrum analysis（EDS） and other physical characterization methods.Starting with the biomass downstream product levulinic acid,2,7-octanedione was synthesized in methanol system with the nano-sized Pt-Ir particle as electrocatalyst.Meanwhile,the experimental results showed that the introduction of Ir improved the electrochemical activity of Pt particles and reduced the amount of Pt and the cost.
