Effect of modified MIL-53 with multi-wall carbon nanotubes and nano fibers on CO2 adsorption

There is a growing need of counter assessing the increase of releases greenhouse gases such as carbon dioxide by researching an alternative technology that can help to reduce carbon dioxide content in atmosphere. This research work investigates the potential of MIL-53 as CO2 capture and storage candidate by conducting an experiment with different pressure between the synthesised and modified MIL-53. To investigate the effect of the Multi-wall carbon nano tubes (MWCNTs) and carbon nano fibers (CNFs) in MIL-53 towards CO2 adsorption performance. The synthesised samples were characterized by Fourier Transform Spectroscopy (FTIR) and Brunauer, Emmett and Teller (BET) techniques. A significant change is observed in the region of the aromatic deformation vibrations due to the different substitution patterns of the aromatic ring. BET surface area for MWCNT@MIL-53 is higher than CNF@MIL-53 and MIL-53. MWCNTs showed the adsorption of CO2 uptake is 0.3mmole-1/g at 100Kpa. © 2014 Trans Tech Publications, Switzerland.
