We present here the electrochemical oxidation of Am(iii) to AmVO2+ and AmVIO22+ in pH 1 nitric acid using a mesoporous tin-doped indium oxide electrode modified with a covalently attached dipyrazinylpyridine ligand.

Ln(iii) complexation by TODGA led to enhanced chemical reactivity with RH˙+ from electron pulse irradiation. Average local ionization energy calculations indicate that this enhancement is likely due to preferential reaction at nitrate counter ions.

UO22+ binds to the surface of a tripolyphosphate modified mesoporous indium tin-doped oxide electrode (nITO|P3). Electrochemical studies reveal that nITO|P3 electrodes catalyze the 2-electron interconversion between UO22+ and U4+, with...
