New equipment for quantitative and qualitative adsorption of volatile organic compound was set up, and using this equipment, adsorption behaviors of various carbob-based nanomaterials and TiO₂ thin films prepared by atomic layer deposition were compared. We could conclud that TiO₂ thin films can show higher adsorption capacity of toluene comparing to the carbon-based nanostructures due to higher affinity of the surface OH groups of TiO₂ towards toluene adsorption. We also demonstrate that our method allows to discriminate reversible and irreversible adsorptions at a given temperature.
