LID - 10.1088/1361-6528/ad27ab [doi] AB - A surface enhanced Raman scattering (SERS) substrate of porous rod-shaped ferric oxide (Fe(2)O(3)) combined with silver nanoparticles (Ag NPs) and black phosphorus (Fe(2)O(3)/Ag/BP) was fabricated to detect the persistent organic pollutants (POPs) at low concentration. The organic pollutant Rhodamine 6G (R6G) was used as the probe molecule to study the performances of Fe(2)O(3)/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 Fe(2)O(3)/Ag/BP was as low as 1.0 x 10(-15)M, which was five orders of magnitude lower than that of Fe(2)O(3)/Ag (10(-10)M). The enhancement factor (EF) of Fe(2)O(3)/Ag/BP was 6.44 x 10(8), which was 3.1 times higher than that of porous rod-shaped Fe(2)O(3)/Ag (2.08 x 10(8)). The Raman signal of R6G based on Fe(2)O(3)/Ag/BP had a good homogeneity, and the relative standard deviation (RSD) of Raman signal intensities of R6G at 1643 cm(-1)was only 5.97%. Furthermore, the Fe(2)O(3)/Ag/BP substrate exhibited a recyclability through the photocatalytic degradation of R6G. The LOD of PCB-3 based on Fe(2)O(3)/Ag/BP was 10(-9)M. Besides, Fe(2)O(3)/Ag/BP had a high SERS activity even it was kept in a centrifuge tube without requiring complicated treatment. These results highlight the potential application of Fe(2)O(3)/Ag/BP for ultra-trace detection of POPs in the environment. CI - (c) 2024 IOP Publishing Ltd.
