- Abstract:
-
The kinetics of the hydrogen oxidation reaction (HOR) on platinum nanoparticles (PtNPs) is explored. The steady-state current for HOR on individual PtNPs is measured via the nanoimpact approach. Adopting the Tafel-Volmer mechanism, the adsorption rate constant for HOR on PtNPs is calculated as 0.020 ± 0.008 m s–1. The HOR is also studied on electrodes where PtNPs are immobilized via drop-casting on the supporting substrate prior to experimentation and the kinetic parameters contrasted with...
