Argon adsorption in channel-like mesoporous carbons at 77 K: Grand Canonical Monte Carlo simulations and pore size analysis

Grand Canonical Monte Carlo simulations were performed for argon adsorption in hexagonal graphitic pores at 77 K. A set of the simulated adsorption isotherms was used as kernel functions in the integral equation of adsorption to obtain the pore size distribution from argon adsorption isotherm measured at 77 K on a mesoporous carbon synthesized in the presence of poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) triblock copolymer template. The resulting pore size distribution is narrow, which is expected for mesoporous carbons obtained by using block copolymers as soft templates.
