How is copper oxide made? It can be formed by heating copper in air at around 300–800°C: 2 Cu + O2 → 2 CuO. For laboratory uses, pure copper(II) oxide is better prepared by heating copper(II) nitrate, copper(II) hydroxide, or basic copper(II) carbonate: 2 Cu(NO3)2(s) → 2 CuO(s) + 4 NO2(g) + O2(g) (180°C)
