Special Issue Information

Dear Colleagues,

In recent decades, single-atom catalyst (SAC), metal−organic framework (MOF) and covalent organic framework (COF) materials have brought about broad interest in regard to their catalytic applications. SACs exhibit a high atomic utilization and specific activity due to their single active site. With the help of recent advances in characterization techniques and theoretical simulations, numerous SACs have been reported to hold excellent activity and selectivity in various chemical reactions. MOFs consisting of metal ions and organic ligands have shown an unprecedented structural diversity. Due to their intrinsic nature, MOFs can act as hosts for the incorporation of metal nanoparticles, or as precursors for the manufacture of SACs, carbon-based materials and those active in catalysis, energy conversion and storage processes, offering great opportunities for the design of functional materials. COFs have expanded the scope of reticular synthesis from MOFs to purely organic counterparts, possessing advantages such as a large surface area, structure tunability, high porosity and excellent stability when directly utilized as catalysts or as support for constructing catalysts. Therefore, we invite the scientific community to contribute to this Special Issue in the form of research or review articles exploring SAC, MOF and COF materials with desirable properties for catalysis, energy conversion and storage.

The activity of emission control catalysts must be improved in urban mode at low temperatures. One possible way is to tailor the metal-support interaction between platinum group metals (PGMs) and ceria to stabilize small clusters or single atoms, optimizing the utilization of costly PGMs. In this study, a small loading of Pd (<0.2 wt. %) was dispersed on Pr-rich cerium–zirconium–praseodymium mixed oxides (CZP45: Ce0.45Zr0.10Pr0.45O2-x). After the initial calcination at 800 °C, Pd was mainly in the form of dispersed isolated cations which were found to be efficient for low-temperature CO oxidation but inactive for propane combustion. Nevertheless, a pre-reduction step can trigger the formation of Pd nanoparticles and promote the propane oxidation. Pd nanoparticles, formed during the reduction step, coupled with the high oxygen mobility of CZP45, lead to outstanding catalytic activity for propane oxidation starting from 250 °C. However, the re-oxidation of Pd nanoparticles and their partial re-dispersion, promoted by the fast oxygen mobility of the mixed oxide, rapidly deactivate the catalysts in lean conditions.
