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
