CeO(2) Enhanced Ethanol Sensing Performance in a CdS Gas Sensor

CdS nanowires (NWs) were fabricated through a facile low-temperature solvothermal method, following which CeO(2) nanoparticles were modified on the NWs. The ethanol sensing characteristics of pure CdS and decorated ones with different CeO(2) content were studied. It was found that the sensing perfor...

description CdS nanowires (NWs) were fabricated through a facile low-temperature solvothermal method, following which CeO(2) nanoparticles were modified on the NWs. The ethanol sensing characteristics of pure CdS and decorated ones with different CeO(2) content were studied. It was found that the sensing performance of CdS was significantly improved after CeO(2) decoration. In particular, the 5 at% CeO(2)/CdS composite exhibited a much higher response to 100 ppm ethanol (about 52), which was 2.6 times larger than that of pure CdS. A fast response and recovery time (less than 12 s and 3 s, respectively) were obtained as well as an excellent selectivity. These results make the CeO(2)-decorated CdS NWs good candidates for ethanol sensing applications.
