Enhanced sensing performance and mechanism of CuO nanoparticle-loaded ZnO nanowires: Comparison with ZnO-CuO core-shell nanowires

The synergism of nanocomposite heavily impacts the performance of gas sensing materials, that need to be systematically and deeply investigated to meet the high application requirement. In this work, we present gas sensors developed by ZnO-CuO core-shell nanowires (C-S NWs) and ZnO/CuO NWs (ZnO NWs modified by CuO nanoparticles) synthesized by a facile three-step process. The sensing performances for both structures were investigated toward the...
