Preparation and characterization of carbon-supported PtRuIr catalyst with excellent CO-tolerant performance for proton-exchange membrane fuel cells
A PtRuIr/C catalyst was prepared using a microwave-irradiated polyol plus annealing (MIPA) synthesis strategy and characterized by a series of techniques. The results are discussed in comparison with those for PtRu/C catalyst prepared in the same way; they show insignificant difference in particle m...

| description | A PtRuIr/C catalyst was prepared using a microwave-irradiated polyol plus annealing (MIPA) synthesis strategy and characterized by a series of techniques. The results are discussed in comparison with those for PtRu/C catalyst prepared in the same way; they show insignificant difference in particle morphology, particle size, size distribution, phase structure, and compositional homogeneity. CO stripping voltammetry and single-proton exchange membrane fuel cell tests reveal that including Ir in the PtRu system results in an excellent CO
ads electro-oxidation activity. Based on exploration of the structure–performance relationship, a speculative mechanism for the superior performance of the PtRuIr/C catalyst is proposed that suggests that the enhanced performance is attributed mainly to the interaction between RuO
2 and IrO
