Cooperative intergrowth effect in LaMnO3, La2CuO4 and CuO three-phase system with broad active window for highly efficient NOx reduction

摘要

The phase composition is tuned to analyze the influence of intergrowth and coexistence in LaMnO3, La2CuO4 and CuO three-phase system in NOx reduction. Among them, different phases of catalyst with LaMnO3 and La2CuO4 two-phase system play a role in the catalytic reaction at different temperatures, thereby maintaining excellent catalytic performance with broad active window from 275 to 1000 degrees C. In addition, this two-phase system is the 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 catalytic system has great value in practical applications.
