近年来，石墨烯和氧化石墨烯修饰的银纳米颗粒被用作表面增强拉曼散射（Sers）基底。然而，它们对大分子化合物的Sers活性检测都是一次性的。为了解决这一问题，降低常规Sers检测的成本，引入了在可见光下具有光催化活性的银/银（Ag/AgCl）。在这项研究中，一种新的，简单的和清洁的方法进行合成的Ag/AgCl/GO复合材料。采用水热法制备Ag/AgCl胶体溶液，然后与GO溶液混合，采用静电自组装法制备Ag/AgCl/GO复合材料。结果表明，Ag/AgCl/GO复合材料对罗丹明6 G具有最佳的Sers活性，最大增强因子为3.8×107。此外，Ag/AgCl颗粒在可见光下具有高效、稳定的光催化活性，使Ag/AgCl/GO复合材料具有出色的自清洁性能。
Recently, silver nanoparticles decorated with graphene and graphene oxide (GO) sheets can be employed as surface-enhanced Raman scattering (SERS) substrates. However, their SERS activity on macromolecular compound detection is all one-time process. In order to solve this issue and decrease the cost of routine SERS detection, silver/silver chloride (Ag/AgCl) with photocatalytic activity under visible light was introduced. In this study, a novel, simple and clean approach is carried out for synthesis of the Ag/AgCl/GO composite. The Ag/AgCl colloidal solution is obtained by hydrothermal method and then mixed with GO solution to obtain the Ag/AgCl/GO composite using a facile electrostatic self-assembly method. Results showed that the Ag/AgCl/GO composite has the optimized SERS activity to Rhodamine 6G molecules with the maximum enhancement factor value of 3.8×107. Furthermore, the Ag/AgCl particles with high efficient and stable photocatalytic activity under visible light lead to an outstanding self-cleaning property of the Ag/AgCl/GO composite.
