| 摘 要： | 采用一锅热熔胶法制备出多孔花状羟基磷灰石/银(HA/Ag)纳米复合材料。通过检测罗丹明B揭示了HA/Ag作为SERS活性底物的独特拉曼增强效应,其检测极限为10~(-8) mol·L~(-1)。在检测中,改变拉曼激光强度,取点位置等手段能有效提高检测的灵敏度。此外,所制备的多孔纳米复合材料HA/Ag作为对硝基苯酚(4-NP)还原为对氨基苯酚(4-AP)反应的催化剂,可以大大缩短反应时间40 min。

| Abstract: | A porous flower-like hydroxyapatite/silver (HA/Ag) nanocomposite was prepared via one-pot sol-thernal method. The unique Raman-enhancing effect of the HA/Ag nanocomposite as the surface-enhanced Raman scattering (SERS) active substrate was revealed by rhodamine B detection at the concentration as low as 10-8 mol·L-1. In the detection, changing the intensity of the Raman laser and the position of the taking points can effectively improve the sensitivity of the detection. In addition, the prepared porous nanocomposite HA/Ag acts as a catalyst for the reduction of p-nitrophenol (4-NP) to p-aminophenol (4-AP), which can greatly shorten the reaction time by 40 min. |
