Surface modification of CoO nanosheets through Cd-doping for enhanced CO sensing performance.

The detection of hazardous CO gas is an important research content in the domain of the Internet of Things (IoT). Herein, we introduced a facile metal-organic frameworks (MOFs)-templated strategy to synthesize Cd-doped CoO nanosheets (Cd-CoO NSs) aimed at boosting the CO-sensing performance. The synthesized Cd-CoO NSs feature a multihole nanomeshes structure and a large specific surface area (106.
