Heterogeneous Electron Transfer Kinetics at Hydrogen- Versus Oxygen-Terminated Electrodes

1 Heterogeneous Electron Transfer Kinetics at Hydrogen- Versus Oxygen-Terminated Electrodes 

There have been many articles written over the last 30 years on how different surface treatments affect the ET characteristics, for both inner- and outer-sphere ET species at BDD. Qualitatively, A values from the C V are reported or quantitative 

Electrode type Boron Redox couple Surface Surface Surface 

MC 1 pm thin (200-800 nm grains) 1020-1021 O.lVs-1 As grown (NDCh,gh) Mild anodic (NDC, ) Severe anodic 

MC 8 pm thin ( 3 pm grains) lO -lO O.lVs-i As grown Cycle from +2 to -1V Acid clean.
