... and stability toward the oxidation of methanol. Finally, comparing Pt–Ru/C (Pt–Ru 20 wt.%, Pt/Ru = 1:1) catalysts with Pt/C (Pt 20 wt.%), the onset potential was 200 mV lower and electrochemical active area was much bigger. impregnating reduction method PtRu/C methanol oxidation fuel cell...

... oxidation on specimens bearing these catalysts (Pt-Ru/CNTs) were investigated via cyclic voltammetry analysis in mixed 1 M methanol and 0.5 M sulfuric acid solutions. It was found that the peak current density of methanol oxidation obtained from the cyclic voltammogram on the new Pt-Ru/CNTs specimen...

... performance for methanol oxidation at 80 ° C . The effect of temperature and time for thermal decomposition was optimized with respect to methanol oxidation, and the catalysts were characterized by cyclic voltammetry, linear sweep voltammetry, scanning electron microscopy, X-ray diffraction studies, and X-ray...

... microscopes aggregation oxidation fuel cells platinum carbon organic compounds SFMCMBs support platinum electrocatalysts methanol oxidation Thanks to their low operating temperature ( 60 - 100 ° C ) and the fast start-up, direct methanol fuel cells (DMFCs) are considered...

...L. X. Yang; R. G. Allen; K. Scott; P. Christensen; S. Roy New PtRu catalyst anodes for methanol oxidation were prepared by a thermal decomposition method on titanium mesh supports. The supports employed were: Single layer (titanium mesh), double layer (two layers of titanium mesh were spot-welded...
