Synthesis of CsPbBr3-loaded Porous Electrospun Nanofibers and is Approach on Visual Colorimetric Detection of Ammonia under Gaseous and Aqueous State |
| 초록 |
In this work, we fabricate porous cesium lead bromide nanofibers (CsPbBr3 NFs) via electrospinning and employ them in a sensor to effectively detect both gaseous and aqeuous ammonia. Porous NFs are modified using the volatile solvent toluene, which is volatilized during the electrospinning process. The applicability of the proposed CsPbBr3 NFs for use under various environmental conditions is verified by analyzing their stability in response to changes in temperature, moisture levell and pH, which are critical drawbacks of CsPbBr3 NCs. Gaseous ammonia (9 ppm) in an N2 carrier is subsequently detected using the photoluminescence (PL) properties of the CsPbBr3 NFs. In addition, an ammonia concentration of 100.0 mg L-1 in an aqueous solution can be detected using the PL intensity, with CsPbBr3 NFs able to selectively detect ammonia due to their non-reactivity with other cations and anions. |
