Abstract
This study introduces a microconductometric sensor, developed by drop-casting 2D-Borophene film on Interdigitated Electrodes (IDEs) for real-time ammonia gas detection. The sensors were exposed to varying concentration ranges of 10–100 ppm and 100-1000 ppm ammonia vapour at room temperature. The results indicated a lower detection limit (LOD) of 4 ppm and high selectivity and reproducibility. The NH3 sensor detected with high sensitivity, quick response, and recovery time of 18 s and 27 s respectively, highlighting the potential and effectiveness of Borophene for gas sensing. More study required to understand the potential mechanisms of this new 2D system and its interactions.
