摘 要: 采用水热碳化-原位还原法合成了银-水热碳球(hydrothermal carbon, HTC)-银(Ag@HTC/Ag)复合材料,并探究复合材料对罗丹明6G(Rhodamine 6G, R6G)的表面增强拉曼散射(surface enhanced Raman scattering, SERS)行为。结果表明:该复合结构具有较高活性,对R6G的检测极限可低至10~11 mol/L,能实现低浓度分子的高灵敏检测。
关 键 词: 复合材料;水热碳化;罗丹明6G;表面增强拉曼散射

Abstract: In this study, we synthesized Ag@hydrothermal carbon(HTC)/Ag composites through hydrothermal carbonization-in situ reduction method and explored the surface enhanced Raman scattering(SERS) behavior of the composites to Rhodamine 6G (R6G). Results showed that the composites were highly active and the detection limit of R6G could be as low as 10-11 mol/L. The composites can detect low concentration molecules with high sensitivity.
