Abstract

Au BPs/MXene mixtures were composited with PVDF membranes by vacuum filtration, which enabled the sensitive detection. It combined electromagnetic mechanism and chemical mechanism to achieve a synergistic enhancement of the detection, resulting in a good stability of the SERS substrate. With fluorescent dyes including rhodamine 6G and methylene blue as templates for the SERS sensor, the SERS substrate possessed high sensitivity and reproducibility on account of the strong interactions between the dye molecules and the Au BPs/MXene. In addition, the photochemical performance of the composite membrane material for rhodamine 6G and methylene blue was investigated, which demonstrated the potential of AuBPs/MXene@PVDF membrane for photochemical applications. The study of the SERS detection and photochemical degradation performance of the composite membrane material in different water sources demonstrated that the excellent testing capability of the AuBPs/MXene@PVDF membrane material can be used for reliable and highly sensitive monitoring and application in water environment analysis.

期刊介绍： Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
