Summary: Ultrathin two-dimensional metal-organic framework nanosheets are promising materials for catalytic, electrochemical, and sensing applications due to their unique features. Activated ligand-cluster units in MOFNs play a crucial role in enhancing surface-enhanced Raman scattering (SERS), making MOFNs highly effective SERS substrates. Integration of inherent ligand-cluster charge-transfer transitions into interfacial charge-transfer processes further enhances the SERS performance of MOFNs.

Summary: In this study, the shell and structural effect of shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) were investigated. It was found that the field enhancement loss due to the shell could be overcome by optimizing the coupling geometry of the shell-isolated nanoparticles (SHINs), and signal enhancement could be further optimized by altering the aggregation geometries of the nanoparticles.

Summary: A magnetic covalent organic framework Fe3O4@BM was prepared and used for the removal of Ag NP. Fe3O4@BM possessed abundant amino groups, positive potential, and rapid separation performance, making it a promising adsorbent. The adsorption process followed the pseudo-second-order kinetic equation and Langmuir isotherm model, with a maximum adsorption capacity of 544.9 mg/g. Furthermore, the recycled Fe3O4@BM@Ag could efficiently catalyze the degradation of 4-nitrophenol and serve as a surface-enhanced Raman substrate for DTNB detection.

Summary: This work presents a metal-free and highly flexible SERS substrate fabricated by chemical oxidation of commercial carbon cloth. The SERS sensitivity of the oxidized carbon cloth is significantly improved by more than 3 orders of magnitude compared to the untreated carbon cloth. The improved SERS performance is attributed to enhanced charge transfer between the oxidized carbon cloth and the adsorbed molecules due to the introduction of rich oxygen-containing functional groups by chemical oxidation. This study paves the way for the design of metal-free and flexible SERS substrates and provides valuable insights for carbon-based SERS substrates.
