![]() At temperatures close to 300 ☌ and above, corrosion should progress at all pHs for neutral and positive applied potentials. We predict the prolonged stability of solid phases at non-standard-state conditions below ≈200 ☌. Elevated temperatures initiate driving forces that increasingly favor corrosion products over passivating oxides. Corrosion phases are found to compete with solid copper precipitates at small applied potentials near neutral pHs. The existing discrepancies between thermodynamically predicted and electrochemically observed behaviors of copper in aqueous electrochemical conditions are addressed. We present the broadly important immunity, passivation, and corrosion behavior of copper subjected to multiple environmental factors, e.g., solution pH, electrode potential, temperature, and pressure, assessed through density functional theory-calculated electrochemical Pourbaix diagrams. ![]()
