Carbon dioxide, which is found with low levels in public indoor spaces, is a representative indicator for indoor air quality. Indoor VOCs also are categorized in indoor air pollutants. Thus this study attempted to prepare a biomass-based activated carbon adsorbent from bamboo stems. Activation focused on forming two size pore channels for simultaneous capture of CO2 and VOCs. To enhance the adsorption capacity, chemical functionalities were doped on the pore surfaces. Differentiated pore channels and chemical interactions between adsorbents and adsorbates could lead to high selectivity. In accordance, in this study, activated carbons were made through a few conditions with physicochemical activation, and tested their CO2/VOCs adsorption under the ambient condition. As a result, micro- and meso-pores were successfully formed, and gas adsorption amount was increased depending on the gas type and reactor structure. |
