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.
