In this work, magnesium oxide (MgO)-modified carbon materials were fabricated using Mg(NO3)2 and microwave-assisted irradiation The properties and textural structures of the prepared materials were characterized using powder X-ray diffraction, elemental analysis, and N2 adsorption/desorption experiments. By changing the microwave reaction time, the spherical structure of the parent material was transformed to a hybrid structure with MgO crystalline particles in a carbon matrix. The morphology evolution and properties of the prepared materials were also investigated using transmission electron microscopy and 77K/N2 adsorption-desorption isotherms, respectively. The CO2 capture performances were also investigated, through isobar experiments under flue gas condition (15% CO2 in N2). It was found that MgO affected the CO2 capture behavior by enhancing the fundamental characteristics of the carbon surfaces. |
