| 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. |
