“…Well‐prepared Ni anodes show an oxidation feature around +4.0 V versus Cu/CuF 2 in HF with low concentrations of water, conductivity additive (e.g., KF) or organic substrate dissolved . This oxidation potential rises significantly when the water concentration in HF is lowered .…”

“…Although previous experiments have suggested the formation of active nickel fluorides such as NiF 3 or NiF 4 on the Ni anode, compelling physical evidence is still missing. Additionally, the electrochemical polarization and passivation behavior of nickel in various electrolytes such as (anhydrous) HF, organic substrates dissolved in HF, and HF‐containing electrolytes such as NEt 3 ⋅ 3 HF have been intensively investigated in the past . However, a detailed understanding of the ECF process is still missing and the active species in a Simons‐type ECF has not yet been clarified.…”

The Simons process, otherwise known as the electrochemical fluorination (ECF) method, is widely used in industry to electrolytically synthesize chemicals for various purposes. Even to this day, the exact mechanism of the ECF reaction remains unknown, but is believed to involve the formation of an anodic nickel fluoride film with highly oxidized nickel centers. In this study, experiments and density functional theory calculations are combined to characterize the initial anodic peak occurring at potentials typically required in an ECF cell. NiF2 is believed to form a passivating layer at low potentials. The calculations show that a potential of +3.1 V is required to oxidize surface Ni2+ centers to Ni3+. This is in good agreement with the measured anodic peak at +3.57 V.
