Direct exposure to toxic and hazardous gases have always been considered as the most pervasive problem worldwide; gradual increase in number of asthma patients due to NOx/SOx gases inhaling, and exposure to 50 ppm formaldehyde gases. To address such issues, development of membranes for selective filtering of target molecules as well as chemical sensors for real-time monitoring of toxic molecules are highly crucial. In this talk, I would like to introduce about advanced porous materials (e.g. MOFs, and graphene) for application in highly sensitive chemical sensors and molecular sieving membrane. Due to the large surface areas of active sensing materials, they showed exceptional detection capability toward toxic gas molecules (e.g. HCHO, H2S, acetone). Furthermore, pore-tuned molecular sieving layer (MOFs, and graphene oxide) combined chemical sensors exhibited further enhanced selectivity because of its filtering effect. |
