Development of high-performance NH3 gas sensor through novel MoSe2/PANI/Ti3C2Tx composite for medical diagnosis and industrial applications
Source abstract
Abstract
Ammonia (NH 3 ) monitoring in environmental and biomedical contexts poses significant challenges due to its impact on sensor sensitivity and selectivity. In the present study, a novel ternary MoSe 2 /PANI/Ti 3 C 2 T x composite was synthesized using hydrothermal and oxidative polymerization techniques for high-performance NH 3 sensing. The newly developed sensor exhibits an exceptional response of 6481.1 upon exposure to 1000 ppm of NH 3 gas at room temperature (28 °C). Notably, the sensor shows an ultrafast response and recovery time of 4.7 s and 18.4 s, respectively, with a limit of detection of 0.6 ppm, along with outstanding selectivity and long-term stability over 90 days. Furthermore, the effect of humidity up to 90% RH and cross-sensitivity over various similar amines was also studied. A wireless IoT-enabled NH 3 leak detection prototype was developed, confirming the sensor’s practical utility. Furthermore, clinical evaluations on uremic patients highlight its promise for non-invasive chronic kidney disease (CKD) monitoring.
