Electrochemical behavior of copper species in the 1-buthyl-3-methyl-imidazolium chloride (BMIMCl) ionic liquid on a Pt electrode

摘要

The electrochemical behavior of Cu(I) and Cu(II) species in the ionic liquid 1-buthyl-3-methylimidazolium chloride, BMIMCI, on a platinum electrode in the interval of 333-363 K, has been investigated. Experiments performed in a controlled N-2 atmosphere cell show that: (i) Cu(I) can be oxidized to Cu(II) and reduced to Cu(0), and (ii) Cu(II) can be reduced to Cu(I) by copper metal according to a comproportionation reaction whose constant has been calculated.
