Abstract:
Detection and differentiation of volatile organic compounds (VOCs) is extremely important since presence of these gaseous pollutants in ambient air is harmful and poses a serious threat to human health even at small concentrations. In this paper, a simple and cost-effective method for synthesis of a nanostructured multilayer film of (CuO/Cu2O)/ZnO:Fe is presented, which allows to form non-planar heterojunctions for efficient vapor detection of volatile organic compounds.
