Abstract
N-type semi-conducting oxides such as SnO2, ZnO and ZrO2 have been known for the detecting materials of inflammable or toxic gases. Of those materials, SnO2-based sensors are well known as high sensitive materials to detect toxic gases. And the sensitivity is improved if catalysts are added. Detecting toxic gases, especially DMMP (di-methyl-methyl-phosphonate) and DPGME(Dipropylene glycol methyl ether), was performed by a mixture of Tin oxide(SnO2) and Zirconia(ZrO2), . The films consist of each three different mass% of Zr(from 1 mass% to 5 mass%), and they were tested by XRD, SEM, TEM, BET. Nano-structure, pore and particle size was controlled to verify the sensor's sensing mechanism. The sensors was evaluated at five different degrees(from 200 ℃ to 400 ℃) and three different concentrations(from 500 ppb to 1500 ppb). The sensors had good sensitivity of both simulants, and high selectivity of DMMP.
