 Abstract
The gas sensing characteristic of composite yolk-shell spheres were investigated. -carbon composite spheres were prepared by ultrasonic spray pyrolysis of aqueous droplets containing Mo-source and sucrose in nitrogen, which were converted into yolk-shell spheres by heat treatment at in air. Subsequently, composite yolk-shell spheres were prepared by the partial sulfidation of . The composite yolk-shell spheres showed relatively low and irreversible gas sensing characteristics at < . In contrast, the sensor showed high and reversible response (S=resistance ratio) to 5 ppm (S=14.8) at with low cross-responses (S=1.17-2.13) to other interference gases such as ethanol, CO, xylene, toluene, trimethylamine, , , and HCHO. The composite yolk-shell spheres can be used as reliable sensors to detect in a selective manner.
