Abstract

In this study, the chemical vapor deposition of methane on the activated carbon has been identified as an effective approach to prepare the CMS for the adsorption of CO2. The effects of deposition parameters on the properties of the CMSs were both experimentally and statistically investigated. The deposition temperature as the most influential factor on the CO2 adsorption capacity was determined based on the response table. CMSs exhibited large volume of narrow-micropore centered at 0.56 nm in size, showed a maximum CO2 adsorption of 1.7275 mmol g(-1) at 273 K and 1 bar. The isosteric heat of adsorption and CO2/N-2 selectivity were 4037 kJ mol(-1) and 22.84 at 273 K and 1 bar, respectively. As a result, this particular study can be used for the main challenges associated with the design of CMS adsorbents to provide a perspective and opportunities to accelerate novel molecular sieve carbon production in the future.
