PROBLEM TO BE SOLVED: To provide an improved three-way catalytic material that allows the reduction of NOx in an oxidizing environment, and a process for reducing NOx in an oxidizing environment.SOLUTION: The invention provides a three-way catalytic material that reduces NOx in an oxidizing atmosphere, and a process for reducing NOx in an oxidizing atmosphere. The three-way catalytic material is a mixed metal oxide catalyst and can be made from a doped barium cerate matrix with a chemical formula of BaADCeO, where A represents a precious metal or a combination of two or more precious metals, D represents at least one transition metal, the coefficient y has a value between 0.0 and 0.20 inclusive, the coefficient z has a value between 0.0 and 0.20 inclusive, and the coefficient δ has a value between 0.00 and 0.20 inclusive.SELECTED DRAWING: Figure 1A |
