저항변화식 가스센서 선택성 향상을 위한 멤브레인 및 촉매 연구동향 = Research Progress in Membrane and Catalyst for Highly Selective Chemiresistive Gas Sensors

다국어 초록 (Multilingual Abstract)

Direct exposure to toxic and hazardous gases has always been considered as the most pervasive problem worldwide, leading to a gradual increase in the number of asthma patients due to NOx/SOx gases inhaling and exposure to 50 ppm formaldehyde gases. Therefore, the development of accurate gas sensors is a key issue for resolving these problems. To address such issues, the development of membranes for selective filtering of target molecules as well as nanocatalyst for enhancing the sensing selectivity is highly crucial. In this review, the research progress for porous membrane materials (e.g. MOFs, and graphene) and nanocatalyst technology for the development of selective and accurate gas sensors will be discussed.
