Metal oxide nanomaterials have been widely utilized in gas sensors due to their excellent performance. Comparing to n-type metal oxides, p-type ones have been less studied for gas sensing applications. In this work, CuO nanoplates were synthesized at different temperatures by a facile hydrothermal route at different temperatures without using any surfactant to study the effect on the gas sensing properties. The morphologies and crystal structures of the synthesized materials were characterized by filed-emission scanning electron microcopy (FE-SEM) and X-ray diffraction (XRD). |
