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 r[r]
