Abstract
A special CdO structure with a bio-inspired morphology was prepared by conversing CdS precursor under annealing treatment. The as-prepared leave-shaped CdO microstructures were further used for developing a sensitive gas sensor to detect acetone and diethyl ether. We find that the biomimetic structure can significantly improve the gas diffusion and adsorption of analytes in the sensing layer of gas sensor. During the gas-sensing process, the target gases can effectively diffuse through the CdO materials and adsorb onto the surface of them. The results show that presented gas sensor exhibits a fascinating gas-sensing performance with high response and short response time towards target gases. Our findings provide a potentially general strategy for developing sensitive gas sensor with enhanced diffusing and adsorbing properties towards analytes.
