다국어 초록 (Multilingual 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 I 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.
