Lanthanide electrochemistry

Electrochemically reacting a lanthanide or actinide in solvent at a working electrode; wherein the solvent comprises an organic solvent such as acetonitrile which have a dielectric constant of at least three; wherein the solvent system further comprises an electrolyte; wherein the working electrode comprises an ionically conducting or permeable film such as a fluorosulfonate film; wherein at least one ligand such as triflate distinct from the ionically conducting or permeable film is present; wherein the ligand is chemically similar to a structure in the ionically conducting or ionically permeable film; and optionally wherein the electrochemical oxidation or reduction is carried out under the influence of a magnetic field which favorably enhances the reaction. Improved electrochemical methods, identification, and separation can be achieved. Also, an electrochemical device, wherein the device is adapted to employ the oxygen reduction reaction (ORR) at the cathode, wherein the cathode is magnetically modified, or the electrolyte comprises at least one lanthanide or actinide, or both.
