摘要 Bimetallic Pd–Co and pure Pt electrocatalysts were evaluated for tolerance to methanol in the oxygen reduction reaction (ORR) in 0.5 M H2SO4 using the tip generation–substrate collection mode of scanning electrochemical microscopy. The Pd–Co electrocatalyst, Pd80Co20 (80% Pd, 20% Co), showed the highest ORR activity among the different Pd–Co compositions, both in the absence and presence of MeOH. The ORR collection efficiency of the electrocatalysts in electrolytes containing various MeOH concentrations were measured and compared, with the Pd80Co20 electrocatalyst showing better tolerance toward MeOH poisoning during ORR than Pt electrocatalysts, especially at high MeOH concentrations.
