The present invention relates to the reduction of materials at low temperatures (<600° C.) by means of microwave radiation without needing to use chemical reducing agents or electrical contacts. It relates more specifically to a method for reducing a material, which comprises the following steps:

Method for directly reducing a material by means of microwave radiation

The invention relates to a catalytic activation layer for use in oxygen-permeable membranes, which can comprise at least one porous structure formed by interconnected ceramic oxide particles that conduct oxygen ions and electronic carriers, where the surface of said particles that is exposed to the pores is covered with nanoparticles made from a catalyst, the composition of which corresponds to the following formula: ABCOwhere: A can be selected from Ti, Zr, Hf, lanthanide metals and combinations thereof; B and C are metals selected from Al, Ga, Y, Se, B, Nb, Ta, V, Mo, W, Re, Mn, Sn, Pr, Sm, Tb, Yb, Lu and combinations of same; and A must always be different from B. 0.01&#x3c;x&#x3c;0.5; 0&#x3c;y&#x3c;0.3.
