润色：First AuMIL-101 Fe has a large number of pores and surface Active site which can adsorb Sulfapyridine molecules onto its surface through physical adsorption This kind of adsorption is nonspecific p

Lastly, the presence of Fe in MIL-101 provides additional active sites for chemical bonding with Sulfapyridine molecules. Fe has a high affinity for nitrogen atoms, allowing for the formation of iron-nitrogen bonds. Moreover, Fe can also form iron-oxygen bonds with the oxygen atoms in Sulfapyridine. These chemical bonds contribute to the strong adsorption and stabilization of Sulfapyridine on the Au/MIL-101 (Fe) surface.

Overall, the combination of physical adsorption and chemical bonding mechanisms allows Au/MIL-101 (Fe) to effectively adsorb and stabilize Sulfapyridine molecules. This enhanced adsorption capacity makes Au/MIL-101 (Fe) a promising material for applications in drug delivery, catalysis, and environmental remediation
