Cerium-Based MOFs as Precursors to Active Oxides for Automotive Soot Oxidation

The development of efficient catalysts for automotive soot oxidation requires precise control over composition, structure, and redox behavior. Cerium-based metal–organic frameworks provide a distinctive platform for designing oxide catalysts, combining well-defined inorganic nodes with chemically tunable organic linkers and multiple opportunities for post-synthetic modification. In this context, Ce-MOF-808 and Ce-UiO-66 derivatives are explored as precursors to nanostructured ceria-based materials. Particular emphasis is placed on how MOF topology, linker functionalization, thermal conversion, and manganese incorporation influence the physicochemical characteristics of the resulting oxides. By establishing relationships between molecular-level precursor design and catalytic function, this approach moves beyond the conventional use of MOFs as porous materials and highlights their potential as tailored precursors for advanced heterogeneous catalysts. The work contributes to the rational development of cerium-based systems for cleaner and more efficient control of particulate emissions.
