| Popis: | 104 Combination of the"nano size" effect and Cl- complexation ability causes massive electrodissolution of Pt (0.42μg cm-2 s-1) under acidic conditions to promote the regeneration of Pt-organic composites. The regeneration of Pt composites modified the morphology of the NF substrate, such that its greatly enhance of the effectiveness and significantly improve the catalytic performance of the O2 reduction reaction, because of the regenerated NF substrate provides an effective dispersion of nPts. The catalytic current density of Pt-organic composite was ~0.32mA cm-2, after the regeneration of Pt-organic, the catalytic current density was 1.88 times (0.6mA cm-2 ) greater than the Pt-organic composite . |
