The surface area, pore volume and adsorption characteristics of metal-organic frameworks (MOFs) are significantly affected by preparation and activation procedures. In this work, we explore one such key synthesis parameter influencing the characteristic of Cu-BTC. We used a solvothermal method to synthesize copper based MOFs (Cu-BTC) using six different solvents (chloroform, dichloromethane, acetone, ethanol, methanol and water) in the activation process. The effects of different activation solvents on the thermal stability, porous structure and CO 2 adsorption of Cu-BTC were investigated. Using methanol as an activation solvent will produce a highly crystalline and nearly solvent-free Cu-BTC, leading to the largest pore volume (0.823 cm 3 g 21 ) and greatest CO 2 adsorption (6.95 mmol g 21 at 25 uC and 132 kPa).
