Highly responsive and selective ppb-level NO2 gas sensor based on mesoporous Pd-functionalized CuO/rGO at room temperature

For the first time, Pd nanoparticle-functionalized, rGO nanosheet-modified 3D rod-like CuO (Pd-CuO/rGO) with nanowire hierarchical structure was successfully synthesized by a facile hydrothermal strategy. Interestingly, the developed Pd-CuO/rGO sensor exhibited...
