Characterization of Magnesium Oxide Nanosheets Prepared by Electrical Wire Explosion Process
Magnesium oxide (MgO) nanosheets were prepared by the electrical wire explosion process under argon protection with a slow release of oxygen into the reacting chamber after the explosion. The structures were studied by field-emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), and Brunauer-Emmett-Teller (BET) measurements. The average size of the nanosheets was 100 to 110 nm and the thickness 3 to 5 nm. The uptake of CO2 by MgO nanosheets was determined under a flow of 100% dry CO2 at atmospheric pressure, which is about 70–85% of the uptake by pure nanopowders, and the maximum value of CO2 adsorption was 3.64 cm3 · g–1.
