Core–Shell Gold Nanoparticles@Pd-Loaded Covalent Organic Framework for In Situ Surface-Enhanced Raman Spectroscopy Monitoring of Catalytic Reactions

“…In addition, the binding energies of S 2p were seen at 162.90 and 164.00 eV, in accordance with organosulfur compounds . As shown in Figure d, the peaks at 340.26 and 335.00 eV could be assigned to Pd 0 3d 3/2 and Pd 0 3d 5/2 , respectively, indicating that PdNPs were successfully formed in the pores of the organic skeleton of COF …”

Furthermore, the catalytic activity of the AuNPs@COF-PdNPs nanostructure was investigated through the reduction of 4-NTP mediated by NaBH 4 .…”

Ferrite Nanoparticles as Catalysts in Organic Reactions: A Mini Review

“…A magnetic-recyclable catalyst, Pd-doped ZnFe 2 O 4 (ZnFe 2 O 4 @PDA/COF@Pd), was synthesized using a covalent organic framework (COF) as a carrier and polydopamine as a crosslinking agent. The catalyst demonstrated excellent catalytic activity in Suzuki coupling and the reduction of p-nitrophenol [108]. The COF prevented the aggregation and leaching of Pd nanoparticles, thereby enhancing the activity and stability of the catalyst.…”
