Abstract

Oxidation of crystalline mineral cuprite in air under ambient conditions, and in alkaline aqueous solution, has been studied by means of potentiometry, voltammetry and X-ray photoelectron spectroscopy. The rest potential of cuprite in pH 9.2 solution in equilibrium with air was at the cuprite/hydrated CuO reversible value. Both electrochemical and spectroscopic data confirmed that cuprite surfaces oxidise under these conditions to form a surface layer of hydrated cupric oxide.
