Impeding Catalyst Sulfur Poisoning in Aqueous Solution by Metal–Organic Framework Composites

Deactivation of noble metal catalysts often occurs in many hydrocarbon reactions. In particular, sulfur species may cause significant poisoning of metal catalysts, even at minimal concentration, due to strong metal–S bond formation. In this work, hierarchical porous composites are prepared by integr...

Description
Summary:Deactivation of noble metal catalysts often occurs in many hydrocarbon reactions. In particular, sulfur species may cause significant poisoning of metal catalysts, even at minimal concentration, due to strong metal–S bond formation. In this work, hierarchical porous composites are prepared by integrating melamine foam with metal–organic frameworks, demonstrating excellent catalytic activity with anti‐sulfur poisoning properties. Several techniques are employed to elucidate the mechanism of anti‐sulfur poisoning. This study offers a functional composite system capable of acting as sulfur‐resistant noble metal catalysts in solution. Excellent anti‐sulfur poisoning performance of metal–organic framework composites in aqueous solution is achieved. This facile strategy offers a functional system for exploring promising applications of sulfur‐resistant noble metal catalysts.
