AbstractProton-exchange membrane fuel cells have been regarded as one of the most promising candidates for efficient energy conversion. However, the CO poisoning of the anode and the scarcity of the Pt metal are two major barriers to their commercialization. Development of CO-tolerant Pd electrocatalysts is considered to be a plausible approach to overcome these problems. Herein we report that for the CO-tolerant H-2 oxidation, sub-2-nm size Pd clusters as well as single atoms, supported on FeOx nanocrystallites, are highly active and durable at a wide temperature range of 20-120 degrees C. Experimental data demonstrated that CO preferentially adsorbs on these small Pd clusters or single atoms linearly, resulting in weakened CO binding and enhanced H-2 competitive adsorption. Therefore, FeOx-supported small Pd clusters or single atoms provide a higher CO-tolerant performance. This finding may offer a new strategy to develop CO-tolerant Pd-based electrodes.
