| Abstract: | A palygorskite/carbon heterogeneous nanocomposite, a unique hybrid of palygorskite and carbon, was prepared and designed as an electrocatalyst support material for PtRuIr nanoparticles and evaluated for methanol electrooxidation. X‐ray diffraction and transmission electron microscopy results showed that PtRuIr nanoparticles were well‐dispersed on the composite support with highly dispersed tiny crystal alloy phase on the surface of PtRuIr amorphous alloy. X‐ray photoelectron spectroscopy results indicated that the formation of Ru and Ir oxides on the surface of the PtRuIr nanoparticles. The electrochemical results show that the palygorskite hybridized carbon used as electrocatalysts support can improve the electrocatalytic activity towards methanol oxidation and CO tolerance. |
