Dioxygen Electroreduction on Electrode Surfaces
Finally, thiocyanate (SCN) adsorption on Au electrode is examined. Both the calculations and the spectroscopy show that three different geometries are adopted by SCN in the potential region studied (0.0 V ≤ E ≤ 1.2 V vs. NHE). At low potential both N-bound and S-bound forms are found, at …

The Electroreduction of Carbon Dioxide on Porous Copper Nanoparticles
… ± 21.5 nm, respectively). Carbon dioxide (CO2) electroreduction (CER) on the Cu nanoparticles synthesized by SSM was confirmed with rotating disk electrode experiments (RDE) using cyclic voltammetry at 25°C in CO2 saturated 0.1M potassium bicarbonate solution (KHCO3) at atmospheric pressure. The …
