Re(bipy-tBu)(CO)3Cl−improved Catalytic Activity for Reduction of Carbon Dioxide: IR-Spectroelectrochemical and Mechanistic Studies
TL;DR: A significantly improved catalyst, Re(bipy-tBu)(CO)(3)Cl (4), for the reduction of carbon dioxide to carbon monoxide was found and shows two one-electron reductions under argon, one reversible at -1445 mV (vs SCE), and one irreversible at -1830 mV.

Electron-Transfer Kinetics of Np3 + ∕ Np4 + , NpO2 + ∕ NpO2 2 + , V2 + ∕ V3 + , and VO2 + ∕ VO2 + at Carbon Electrodes
Abstract: Like vanadium redox couples (V 2 + /V 3 + and VO 2 + /VO + 2 ), neptunium is a good candidate for the active materials of a redox-flow battery because it possesses two isostructural and reversible redox couples (Np 3 + /Np 4 + and NpO + 2 /NpO 2 + 2 ). The standard rate constants k 0 of the neptunium electrode reactions were first determined at four types of carbon electrodes. The k 0 values for Np 3 + /Np 4 + and NpO + 2 /NpO 2 + 2 are 1.9 X 10 - 2 and 1.5 X 10 - 2 cm s - 1 , respectively, at the c plane of pyrolytic graphite [PG(c plane)] and also 1.4 × 10 - 2 and 2.1 × 10 - 2 cm s - 1 , respectively, at plastic formed carbon (PFC). The standard rate constants for the V 2 + /V 3 + and VO 2 + /VO + 2 electrode reactions were also first determined at PG(c plane) and PFC electrodes. The determined k 0 values are larger at the PFC electrode, k 0 = 5.3 × 10 - 4 and 8.5 × 10 - 4 cm s - 1 for V 2 + /V 3 + and VO 2 + /VO + 2 , respectively, than at the PG(c plane) electrode. There is about a 10 2 order of difference between the k 0 values of neptunium and vanadium ions, and this difference was discussed in reference to the homogeneous electron-exchange rate constants of these redox couples.

TL;DR: In this paper, the integral equations obtained from the boundary value problems were solved and extensive data were calculated which permit construction of stationary electrode polarograms from theory, making it possible to develop diagnostic criteria so that unknown systems can be characterized by studying the variation of peak current, half-peak potential, or ratio of anodic to cathodic peak currents as a function of rate of voltage scan.
