AB - Sensing of volatile organic compounds (VOCs) is a growing research topic because of the concern about their hazard for the environment and health. Furan is a VOC produced during food processing, and it has been classifed as a risk molecule for human health and a possible biomarker of prostate cancer. The use of carbon nanotubes for VOCs sensing systems design could be a good alternative. In this work, a theoretical evaluation of the interactions between furan and zigzag single-wall carbon nanotubes takes into account diferent positions and orientations of the furan molecule, within a density-functional theory frst-principles approach. The van der Waals interactions are considered using diferent exchange-correlation functionals (BH,C09, DRSLL and KBM). The results indicate that vdW-functionals do not signifcantly afect geometry; however, the binding energy and the distance between furan and nanotube are strongly dependent on the selected exchange-correlation functional. On the other hand, the efects of single and double vacancies on carbon nanotube are considered. It was found that the redistribution of charge around the single-vacancy afects the bandgap, magnetic moment, and binding energy of the complex, while furan interaction with a double-vacancy does not considerably change the electronic structure of the system. Our results suggest that to induce changes in the electronic properties of carbon nanotubes by furan, it is necessary to change the nanotube surface, for example, by means of structural defects.
