The detection of nitrogen dioxide (NO2) is essential for the environment and human health. Tin dioxide (SnO2) based sensors have demonstrated capabilities to detect NO2, while their response, response/recover speed and selectivity are not good enough for their practical applications. To address these issues, the SnO2 nanoparticles doped with reduced graphene oxides (rGO) have been synthesized by using...
Through thermally treating silicon nanoporous pillar array (Si-NPA) in a graphite crucible in a vacuum furnace at 1100°C, a continuous thin film composed of cubic SiC nanoparticles was prepared and its room-temperature resistive sensing properties were measured. The sensor was found to be with high sensitivity and an upper limit concentration of 1200ppm for H 2 S detection. Through carrying...
