Título: | Improving Sensitivity of a Chemoresistive Hydrogen Sensor by Combining ZIF-8 and ZIF-67 Nanocrystals |
Autor: | Matatagui, Daniel CSIC ORCID; Sainz-Vidal, Arianee; Gràcia, Isabel; Figueras, Eduardo; Cané Ballart, Carles; Saniger, José | Fecha de publicación: | 28-ago-2017 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Proceedings 1 (4): 462 (2017) | Resumen: | In the present work, nanostructures of zeolitic imidazolate frameworks (ZIF-8 and ZIF-67) were combined to obtain a novel chemoresistive sensor, improving the sensitivity of ZIF-67 and facilitating measurement of ZIF-8 by decreasing the resistivity. The sensor detected concentrations as low as 10 ppm of hydrogen increasing its resistivity about 4.5 times. The response of the sensor was compared with a similar chemoresistive sensor based exclusively on ZIF-67, and the sensitivity was around three times higher in the case of the sensor with ZIFs combination. | Versión del editor: | http://dx.doi.org/10.3390/proceedings1040462 | URI: | http://hdl.handle.net/10261/158507 | DOI: | 10.3390/proceedings1040462 | E-ISSN: | 2504-3900 | Identificadores: | doi: 10.3390/proceedings1040462 |
