Adsorbed hydrogen as a site-blocking species in the electrocatalytic oxidation of formate on Pd/C in alkaline medium |
| 초록 |
We investigate the oxidation of HCOO- on Pd/C in alkaline medium using H/D kinetic isotope effect studies and various electrochemical experiments. We first reveal that HCOO- is oxidized to CO2 through a direct pathway, and the oxidation of Hads is the rate determining step (RDS) in the oxidation of HCOO-. We reveal that the slow oxidation kinetics of Hads serving as a site-blocking species inhibits the oxidation of HCOO-, and a more significant site-blocking effect is observed in the potential region for Hads. These observations are expected to provide clues to understanding the outstanding activity of Pd and rational approaches for the development of more active catalysts for the oxidation of HCOO- in alkaline medium. |
