Effect of Morphology of MgO on the CO2 Adsorption Capacity for Low Temperature Applications
MgO nanoparticles, nanoflakes and nanorods were synthesized by sol-gel or hydrothermal method. X-ray diffraction confirmed the formation of cubic MgO in entire samples after calcination. The round particles diameter was in the range of 200-500 nm while the flakes structure were with thickness 100-200 nm. The rods were in average diameter of 150-500 nm. CO2 adsorption capacity was measured by using TGA. MgO flakes with smaller crystallite size demonstrated high CO2 adsorption capacity of 1.738 mmol/g at low adsorption temperature of 50°C.
