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.
