Synthesis, characterization and electrocatalytic activity for ethanol oxidation of carbon supported Pt, Pt-Rh, Pt-SnO2 and Pt-Rh-SnO2 nanoclusters
Апстракт
Nanoclusters of Pt, Pt-Rh, Pt-SnO2 and Pt-Rh-SnO2 were successfully synthesized by polyol method and deposited on high-area carbon. HIRTEM and XRD analysis revealed two phases in the ternary Pt-Rh-SnO2/C catalyst: solid solution of Rh in Pt and SnO2. The activity of Pt-Rh-SnO2/C for ethanol oxidation was found to be much higher than Pt/C and Pt-Rh/C and also superior to Pt-SnO2/C. Quasi steady-state measurements at various temperatures (30-60 degrees C), ethanol concentrations (0.01-1 M) and H2SO4 concentrations (0.02-0.5 M) showed that Pt-Rh-SnO2/C is about 20 times more active than Pt/C in the potential range of interest for the fuel cell application.
