In situ infrared CO detection using silver loaded EMT zeolite films

“…In the case of CO sensing, it is very important for the detection in this range since human health can be harmed by CO with more than 30 ppm. 37 Considering that the optical path in the IR machine was lled with nitrogen, the detected CO 2 should be in the cell and comes from the transformation of oxidized CO. Note that the size of the individual zeolite nanocrystals and the thickness of the lms are comparable, while the silver contents in samples are 0 wt%, 9 wt%, and 18 wt% from ICP analysis, respectively, which is also in good accordance with the changes of the CO 2 intensity.…”
