The CuO/Cu2O nanostructured films were synthesized via a simple chemical solution based method (SCS). The morphological properties were investigated using a scanning electron microscope (SEM). The elaborated sensors based on nanocrystalline films of CuO/Cu2O were tested to hydrogen gas. It was observed that thermal treatment at different temperatures in air can induce changes in morphology of the films and also change the gas response to the tested gas. The gas sensing mechanism of non-planar CuO/Cu2O films to the hydrogen gas was proposed.
