Chem Commun (Camb). 2024 Apr 19. doi: 10.1039/d4cc01275e. Online ahead of print.ABSTRACTNOx is an air pollutant that affects human health. A series of perovskite catalysts with different ratios of lanthanum, iron, and manganese and a three-dimensional ordered microporous structure was prepared, and the strongest catalytic performance was obtained with the LaFe0.1Mn0.9O3 catalyst. LaFe0.1Mn0.9O3 possesses the greatest number of oxygen vacancies and reached 77% NO oxidation conversion at 250 °C, with the highest NO oxidation conversion of 99% at 318 °C. This work provides a promising non-precious metal catalyst for NO oxidation and soot combustion.PMID:38639479 | DOI:10.1039/d4cc01275e
