Polarographic and redox potential studies on copper(I) and copper(II) and their complexes

Electrical power production from low-grade waste heat using a thermally regenerative ethylenediamine battery

“…(3)) compared to that of copper complexed with ammonia (-0.04, Eq. (2)) [24]. The improved anode potential with the higher ethylenediamine concentration was consistent with potentials predicted by the Nernst equation (Eq.…”

Solvothermal and mechanochemical intercalation of Cu into La2O2S2 enabled by the redox reactivity of (S2)2− pairs

“…16 In particular, ethylenediamine (en) strongly favors the formation of cupric complexes ([Cu(en)2] 2+ or [Cu(en)3] 2+ ) 17 over their cuprous counterparts. 18 While this disproportionation process is often employed for seeding copper (nano)crystals, 19 Cui and co-workers recently demonstrated also that the in situ formed Cu 0 species have the ability to fit into host lattices such as observed for Bi2Se3, MoO3, Sb2Te3, In2Se3 and GaSe. [20][21] We can expect a similar result for La2O2S2; namely, Cu 0 species formed by disproportionation of Cu + salts may react with (S2) 2dimers embedded in La2O2S2.…”

Electromodulated release of nitric oxide through polymer material from reservoir of inorganic nitrite salt

“…EDTA was added to help drive the reduction reaction of Cu(I) with nitrite (Cu(I) + NO 2 - + 2H + → Cu(II) + NO + H 2 O) to the product side via the stronger chelation of Cu(II) (than Cu(I)) by EDTA. 22,23 Under these conditions, continuous application of either only the reduction potential (-0.7 V) or only the NO liberation potential (+0.2 V) to the copper electrode does not result in any significant long-term NO generation. Note that the applied voltage cycle employed in Figure 1 is -0.7 V for 3 min, then +0.2 V for 3 min, and this sequence is continuously repeated.…”
