Abstract:A surface enhanced Raman scattering (SERS) substrate of porous rod-shaped Fe2O3 combined with Ag nanoparticles (NPs) and black phosphorus (Fe2O3/Ag/BP) was fabricated to detect the persistent organic pollutants at low concentration. The organic pollutant Rhodamine 6G (R6G) was used as the probe molecule to study the performances of Fe2O3/Ag/BP, and 4-chlorobiphenyl (PCB-3) was the target of detection. The limit of detection (LOD) of R6G based on this novel SERS substrate Fe2O3/Ag/BP was as low as 1.0 × 10-15 M… Show more
