N-GQDs incorporated SnO2 nanotubes by electrospinning for ammonia sensor with enhanced performance |
| 초록 |
Pure and N-GQDs (Nitrogen doped graphene quantum dots) incorporated SnO2 nanotubes (NTs) were fabricated by a one-step electrospinning method. The structure, morphology, chemical state and specific surface area were analyzed. The SnO2 nanotubes consists of tens of thousands of SnO2 nanoparticles with an ultra-small grain size. The as-synthesized pure and N-GQDs incorporated SnO2 nanotubes were used to fabricate gas sensor. It was found that the gas response toward 100 ppm of ammonia was improved from 6.48 to 82.44 at room temperature, through the activation by N-GQDs. And the results indicate that the sensor based on N-GQDs incorporated SnO2 not only has ultrahigh sensitivity but also possesses good response–recovery properties, linear dependence, repeatability, selectivity and long-term stability, demonstrating the potential to use N-GQDs incorporated SnO2 nanotubes as ammonia gas sensors. 2019년 한국교통대학교 지원을 받아 수행하였음. |
