A method to prepare a thin ceramic or metallic solid-state composition comprising three phases: a material (A), a material (B), and pores, wherein the porous matrix of material (A) has a porosity gradient in the range of about 0% to about 80%, and wherein the pores are partially or completely filled
A method to prepare a thin ceramic or metallic solid-state composition comprising three phases: a material (A), a material (B), and pores, wherein the porous matrix of material (A) has a porosity gradient in the range of about 0% to about 80%, and wherein the pores are partially or completely filled with material (B). Various compositions and methods of use for the prepared composition are also disclosed.

1. A mixed ionic/electronic conducting membrane that comprises a thin solid composition consisting of at least one component of a ceramic material (A) said thin solid composition having within said material (A)a surface concentration gradient consisting of at least one component of a ceramic and metallic material wherein said material (A) is selected from the oxides of formula (I): (MaOb)1-x(RcOd)x (I),wherein M is at least one trivalent or tetravalent atom selected from the group consisting of Bi, Ce, Zr, Th, Ga, and Hf;wherein a and b are such that the structure MaOb is electrically neutral;wherein R is at least one divalent or trivalent atom selected from the group consisting of Mg, Ca, Ba, Sr, Gd, Sc, Yb, Y, Sm, Er, In, Nb, and La;wherein c and d are such that the structure RcOd is electrically neutral;and wherein x is in the range of about 0.05 to about 0.30. 2. The mixed ionic/electronic conducting membrane according to claim 1, wherein said x is in the range of about 0.075 to about 0.15. 3. The mixed ionic/electronic conducting membrane according to claim 1, wherein said material (A) is selected from the stabilized zirconias of formula (Ia): (ZrO2)1-x(Y2O3)x (Ia)wherein said x is in the range of about 0.05 to about 0.15. 4. The mixed ionic/electronic conducting membrane according to claim 1, wherein said membrane is a catalytic membrane reactor adapted to produce syngas by the catalytic reaction of natural gas. 5. The apparatus mixed ionic/electronic conducting membrane according to claim 4, wherein said reaction further comprises steam and oxygen, and wherein said oxygen is obtained by separating it from air, and by mixing ionic/electronic conduction through said membrane. 6. The mixed ionic/electronic conducting membrane according to claim 1, wherein said membrane is adapted to synthesize an organic compound from hydrocarbon-based molecules-through at least one catalytic or non-catalytic oxidation step using gaseous oxygen, and wherein said oxygen is obtained by separating it from air, by mixed ionic/electronic conduction through said membrane.
