A composite of metal-organic frameworks (MOF) and carbon nanotubes (CNTs) acts as a CO₂ sensor due to the resistance change of the CNTs by the selective molecular adsorption of the MOFs. Sensing ability is expected to be affected by the crystal size of MOF and the carrier density of CNTs, but CNT/MOF with these properties controlled have not been reported to date. In this study, we will report the successful fabrication of CNT/MOF with controlled crystal size and carrier density and evaluate their CO₂ response.
