Abstract

The authors reported the gas-phase CO₂ and NH₃ adsorption characteristics of Ag-decorated carbon nanotubes (CNTs). High-density CNTs were grown on an oxidized Si substrate by thermal chemical vapor deposition. The average length and diameter of the CNTs were approximately 4.52 μm and 45 nm, respectively. Ag nanoparticles were coated onto the nanotube surfaces to a thickness of approximately 7 nm. The Ag-coated CNTs were sensitive to CO₂ and NH₃ vapors and could be used to provide a sensor for these gases. The Ag-decorated samples showed stable, reproducible responses and good recovery.
