Abstract—Metal-organic frameworks (MOFs) have attracted
much attention as adsorbents for the separation of CO2 from
flue gas or natural gas. A copper-based metal-organic
framework and graphite oxide composite (HKUST-1/GO) was
synthesized and characterized using X-ray diffraction, sorption
of nitrogen and scanning electron microscopy. The composite
improved the CO2 adsorption capacity and CO2/N2 selectivity.
The composite obtained exhibited about a 38 % increase in CO2
storage capacity than the parent MOF HKUST-1 at 305 K and 5
atm.
Index Terms—Carbon dioxide adsorption, composites,
high-pressure adsorption apparatus, metal-organic
frameworks.
