Advanced Physical Adsorption Characterization of Nanoporous Carbons: Assessing Surface (Chemistry) Properties and Pore Structure by a Combination of Water, Argon/Nitrogen and Carbon Dioxide Adsorption

摘要

Activated carbons (ACs) are generally well-suited for water purification applications. In order to optimize these applications one needs, among other requirements, a comprehensive characterization of the adsorbent. Within this context, our study aims at the following: (i) Comprehensive and state-of-the art structural characterization of nanoporous active carbon materials by physical adsorption; (ii) evaluation of surface chemistry by applying various experimental methods (see below); (iii) water adsorption measurements and their interpretation by taking into account pore structure and surface chemistry of the active carbon adsorbent.
