Summary: In this study, three-dimensional Ag aerogel-supported Hg single-atom catalysts were used as an efficient SERS substrate for monitoring enhanced oxidase-like reactions. The effect of Hg2+ concentrations on the SERS properties of 3D Hg/Ag aerogel networks was investigated, and an optimized addition of Hg2+ resulted in specific enhancement. The formation of Ag-supported Hg SACs was confirmed using HAADF-STEM imaging and XPS measurement, and the oxidase-like catalytic mechanism of Hg/Ag SACs was revealed using DFT. This research provides a mild synthetic strategy for fabricating Ag aerogel-supported Hg single atoms with promising prospects in various catalytic fields.

Summary: Flexibility and self-cleaning are important areas of research in the development of plasma substrates in Surface-enhanced Raman scattering (SERS). This study presents a flexible composite Au@Ag/ultrathin g-C3N4/Graphene (AUG) film, based on a PDMS film, used as a highly sensitive SERS substrate for detecting rhodamine 6G (R6G) molecules. The AUG flexible composite film displayed a detection limit of 10-12 M for R6G molecules, maintained 83% of SERS activity after 10 photocatalytic cycles, and had only a 5% decrease in SERS detection performance after 30 days of storage in air. The facile fabrication process makes the AUG composite film an excellent candidate for flexible, inexpensive, and stable wearable SERS sensing systems.
