Enhanced CO oxidation via synergistic interactions of Pd and phosphotungstic acid confined within MIL-101(Cr).

ABSTRACT: Metal-organic frameworks (MOFs), particularly MIL-101(Cr), are promising catalytic supports due to their exceptional surface area and porosity. While noble metals like palladium (Pd) and polyoxometalates, such as phosphotungstic acid (PA), exhibit intrinsic catalytic activity, their application is limited by Pd agglomeration and PA's low surface area and recovery issues. This study addresses these limitations by using MIL-101(Cr) to simultaneously disperse and stabilize Pd and PA, leveraging the MOF's mesoporous architecture to confine these components, inhibiting agglomeration and leaching, and maximizing accessibility and catalytic efficiency. This integrated catalytic system, combining the redox activity of Pd and the Brønsted acidity of PA within the robust MOF framework, is designed t
