摘要: A Pt-MoO3/C catalyst, aimed to eliminate the harmful effect of sulfur dioxide (SO2) on the performance of Pt nanoparticles (NPs) for catalysis of oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFC), is developed and characterized by TEM, XRD and XPS. The results reveal that Pt-MoO3/C catalyst exhibits not only a higher catalytic activity, but also a better SO2 poisoning resistance and a better recovery performance than the commercial Pt/C catalyst does.
