Direction of dimethylmethylphosphonate(DMMP) using activated carbon fibers based gas sensor |
| 초록 |
In this study, the influence of microporous structure of activated carbon fibers (ACF) on dimethyl methylphosphonate (DMMP) gas detection properties was investigated. The pore structure was given to carbon fibers by chemical activation process, and an electrode was fabricated for gas sensors by using these fibers. fibers. The PAN based ACF electrode, which is an N-type semiconductor, received electrons from a reducing gas such as DMMP, and then electrical resistance of its electrode finally decreased because of the reduced density of electron holes. The sensitivity of DMMP gas detection increased from 1.8% to 5.6% as the specific surface area and micropore volume increased. It is attributed that as micropores were formed for adsorbing DMMP whose molecular size was 0.57 nm, electron transfer between DMMP and ACF was facilitated. |
