摘要: Herein, a self-powered electronic nose strategy with highly selective gas detection is described. The two-dimensional microarray based on the triboelectrification between ZnO nanowires and dielectric layers, heterogeneous catalytic reaction occurring NiO nanoparticles. These noses show ability to distinguish four volatile organic compound (VOC) gases (methanol, ethanol, acetone, toluene) limit of 0.1% at room temperature using no external power source.
