The phase composition was tuned to discuss the intergrowth and coexistence effect for LaCu_0.5Mn_0.5O₃ catalysts in NO_x reduction. The two-phase system consisting of LaMnO₃ and La₂CuO₄ had been thoroughly studied. Different phases in this two-phase system play the key role in NO_x reduction at different temperatures, thereby maintaining excellent catalytic performance with broad active window from 300 to 1000 °C. In addition, this two-phase system was the first catalytic system to perform well in all of the following aspects, with decent practicability, superior long-term catalytic ability, excellent cyclic catalytic ability, reliable water and sulfur resistance, low toxicity, low cost, high reserves, and strong stability in high temperature range. This two-phase system had great value in practical applications. Furthermore, by the results of in situ DRIFTS and quasi-in situ XRD and XPS, the reaction mechanism was tentatively described in NO_x reduction.
