Methane Adsorption on Cu-BTC110 Metal-Organic Framework

Resumo

Cu-BTC110 metal-organic framework has been synthesized by solvothermal method using N,N '‑dimethylformamide organic solvent at 110°C. Cu-BTC110 sample has the following adsorption characteristics: micropore volume W₀ = 0.38 cm³/g, specific surface area S_BET = 850 m²/g, micropore radius х₀ = 0.36 nm, standard characteristic energy of benzene adsorption Е₀ = 33.6 kJ/mol. Methane adsorption on a Cu-BTC110 sample at temperature from 210 to 293 K and pressure up to 140 kPa has been studied. Differential molar heat of methane adsorption has been calculated from adsorption isosteres.
