The Horváth-Kawazoe (HK) method was developed for determining the pore size distribution of graphitic slit pores in microporous carbons using N2 adsorption measurements at 77 K (Horváth and Kawazoe, 1983). The method assumes that pores of a given width will fill at a particular relative pressure, which is determined by the use of a 10-4 potential to describe the interaction between the adsorbate molecules and the pore wall (Everett and Powl, 1976).
