1. A process for removing oxygen from an oxygen containing gas mixture comprising the steps of:

  • providing a partially oxidized form of a metal carbonate selected from the group consisting of manganese carbonate, iron carbonate, nickel carbonate and cobalt carbonate, wherein said partially oxidized form of metal carbonate has a crystallite particle size of less than about 0.08 microns;

    contacting said partially oxidized form of metal carbonate with said gas mixture; and

    adsorbing said oxygen from the gas mixture without generating water to produce a purified gas.
