Adsorbate-adsorbate interactions on microporous materials

Simple isotherm models can fit microporous adsorption yet the molecular interactions underlying successful fitting have often remained obscure. Here we demonstrate how semi-empirical model data be mined to reveal reality of adsorbate-adsorbate interactions. This was made possible by fluctuation theory, a rigorous theory based only on principles statistical thermodynamics. For carbons, quantified from Dubinin-Radishkevich (DR) and Dubinin-Astakhov (DA) successfully capture primary micropore filling mechanism subsequent layer adsorption, leading liquid-like behaviour adsorbates. The microscopic meanings DR DA parameters potential also been clarified via
