Abstract:
Carbon dioxide (CO2) is the main greenhouse gases emitted today. CO2 concentration in the atmosphere has increased, because of the intensive use of fossil fuels. MIL-101 or Cr3(F,OH)-(H2O)2O[(O2C)-C6H4-(CO2)]3.nH2O (n 25), is one of the metal organic frameworks with Lewis acid sites that can be activated by removal of guest water molecules. In this study, we synthesized metal organic framework MIL-101 and then with multi walled carbon nanotube (MWCNT) incorporation. For synthesis of this composite, well dispersed MWCNTs in dimethyl formamide were mixed with a hydrofluoric acid solution of chromium nitrate nona hydrate and terephthalic acid. The MWCNT@MIL-101 obtained had the same crystal structure and morphology at those of virgin MIL-101, but carbon dioxide adsorption capacity enhanced about 40% at 298 K and 10 bar. The increment in the CO2 adsorption capacity of MWCNT@MIL-101 was attributed to the increase of micropore volume of MIL-101 by MWCNT incorporation.
