Highly sensitive and selective NO2 gas sensor fabricated from Cu2O-CuO microflowers

Three-dimensional (3D) hierarchical Cu2O-CuO microflowers assembled by nanorods were successfully obtained through an environmentally friendly hydrothermal route. Compared with other gases, the Cu2O-CuO microflowers-2 sensor had excellent selectivity, repeatability and long-term stability to NO2 at...
