摘要：
Carbon monoxide (CO) gas sensors operating at room temperature were fabricated using rutile tin oxide and hexachloro-platinic acid to get a high dispersion rate of platinum in the tin oxide. The sensor material was analyzed by EDS, TG/DTA, SEM and FTIR. The number of chemisorbed atom per unit area and sensor sensitivity were related by space charge model. Gas sensing characteristics were investigated as a function of Pt content, heat-treatment temperature and operating temperature. The humidity dependence of the fabricated sensors is also discussed.
