An electrochemical process for producing unsaturated hydrocarbon compounds from unsaturated hydrocarbon compounds and for extracting oxygen from a gas containing N2O, NO, NO2, SO2, or SO3 is described. The process is characterized by the use of mixed metal oxide materials having a perovskite structure represented by the formula: AsA′tBuB′vB″wOx wherein A represents a lanthanide or Y, or a mixture thereof; A′represents an alkaline earth metal or a mixture thereof; B represents Fe; B′represents Cr or Ti, or a mixture thereof; and B″represents Mn, Co, Vi, Ni or Cu, or a mixture thereof.
