Soot and Carbon Monoxide Combustion on Lanthanum-Based Perovskite Materials

Perovskite-type materials were studied as soot and carbon monoxide combustion catalysts. We used a combination of first-principles, density-functional-theory calculations with temperature programmed reduction measurements, X-ray diffraction, and carbon black and carbon monoxide oxidation measurements to elucidate the processes that contribute to catalytic activity and structural stability of these materials.
