Influence of CO 2 and H 2 O on the air oxidation reaction of Mg nanoparticles has been investigated by Mg K-edge NEXAFS technique. The water vapor in the air causes rapid progression on the air oxidation reaction of the Mg nanoparticles. The basic magnesium carbonate (4(MgCO 3 ).Mg(OH 2 ).4(H 2 O) : BMC) is formed by the long term exposure to air. The NEXAFS analysis shows an existence of several intermediates of the BMC formation reaction.
