There is growing interest in developing a multifunctional surface-enhanced Raman scattering (SERS) substrate to deal with the challenge in the pretreatment-free detection and degradation of hazardous organic pollutants in water. Herein, a hydrophilic–hydrophobic graphitic carbon nitride@silver (g-C3N4@Ag) hybrid substrate was exploited as a potential candidate for the recyclable detection of dye molecules. Such a sophisticated substrate not only showed a significant SERS activity with a high enhancement factor of 3.21 × 106 triggered by the significantly aggregated Ag nanoparticles, but also possessed an outstanding self-cleaning property via visible-light irradiation. Furthermore, the effective weakening of the coffee-ring effect was also facilitated by the hydrophilic–hydrophobic structure, resulting in excellent uniformity and reproducibility. Ultimately, the applicability of the developed recyclable SERS substrate in the monitoring of trace malachite green was demonstrated. It is expected that the innovative SERS substrate has great potential for application in highly sensitive, stable, and recyclable on-site analysis, especially for organic pollutant treatment and environmental protection.

一种亲水-疏水石墨氮化碳@银混合基板，用于可回收的表面增强拉曼散射检测，无咖啡环效应
开发多功能表面增强拉曼散射 (SERS) 基底以应对水中有害有机污染物的无预处理检测和降解挑战的兴趣越来越大。在此，亲水-疏水石墨氮化碳@银（gC 3 N 4 @Ag）杂化基底被用作染料分子可回收检测的潜在候选物。这种复杂的基底不仅表现出显着的 SERS 活性，由显着聚集的 Ag 纳米粒子触发，具有 3.21 × 10 6的高增强因子，而且通过可见光照射。此外，亲水-疏水结构也促进了咖啡环效应的有效减弱，从而获得了优异的均匀性和重现性。最终，证明了开发的可回收 SERS 基材在监测痕量孔雀石绿中的适用性。预计这种创新的SERS基底在高灵敏度、稳定和可回收的现场分析中具有巨大的应用潜力，特别是在有机污染物处理和环境保护方面。
