Abstract

An ethanol-sensing powder (La₂O₃@Sb-SnO₂), mixture composed of 1.00 wt.% La₂O₃ and 99.00 wt.% Sb-doped SnO₂ (Sb-SnO₂), was found to possess enhanced sensitivity towards ethanol: typically, for La₂O₃@Sb-SnO₂, the ratio of the response towards 1000 ppm ethanol vapor to that of 1000 ppm CO is 26.1 (60.0/2.3) under operating temperature of 250 °C; while for Sb-SnO₂, the ratio is only 4.5 (9.0/2.0). A suggestive mechanism on enhanced ethanol sensing is discussed.
