Electroreduction of Molybdate Ions in the Presence of Hydrofluoric Acid

“…The second process is due to a rise in the diffusion permeability of the cathodic film, which acts as a kind of negative feedback. A similar effect of a potential-independent effective activation energy has also been observed for the anodic dissolution of nickel [10,11].…”

Possibility of Depositing Electrolytic Manganese Dioxide onto Titanium Anodes from Manganese Chloride Solutions

“…As the anode material for electrolysis of MnCl 2 solutions were used iridium [3], platinum [4], lead coated with lead dioxide [4], graphite [5], ORTA, and titanium electrodes coated with titanium carbide or manganese dioxide [6 3 8]. Because platinum and iridium are very expensive metals, it is unreasonable to use them in industrial electrolysis.…”

“…At a potentials of approximately up to 1.5 V, Mn 2+ is oxidized in solution to Mn 3+ [equation (3)]. Another electrode reaction [equation (4)] takes place when the potential increases to 1.8 V.…”

Corrosion of Lead and its Alloys

“…70 The corrosion rate and current efficiency of anodes can be improved significantly by the incorporation of minor amounts of foreign species in the electrolyte. 70 The corrosion rate and current efficiency of anodes can be improved significantly by the incorporation of minor amounts of foreign species in the electrolyte.…”
