摘　　要：以牡蛎壳为原料,利用水热法合成高纯度的羟基磷灰石(HAP)载体,经磷酸银负载后,制备出纳米棒状Ag3PO4/HAP复合光催化剂。利用扫描电镜(SEM)、高分辨透射电镜(HRTEM)、X射线衍射(XRD)、X射线光电子能谱仪(XPS)对样品进行表征,并考察不同的制备因素对催化剂降解亚甲基蓝溶液性能的影响。结果表明,当质量比为1∶2时制备的1∶2-Ag3PO4/HAP催化剂的表现最为突出,在10 min时即可达到50%的降解率,在40 min时基本降解完全,是一种高效的复合光催化剂。High-purity hydroxyapatite(HAP)was prepared from oyster-shell waste by a hydrothermal method and was used as the carrier for Ag3PO4,resulting in the preparation of a nanorod-like Ag3PO4/HAP composite photocatalyst.Scanning electron microscopy(SEM),high-resolution transmission electron microscopy(TEM),X-ray diffraction(XRD),and X-ray photoelectron spectroscopy(XPS)were used to characterize the prepared photocatalyst and to explore the effect of different preparation parameters on the catalytic activity of the photocatalyst toward the degradation of a methylene blue solution.The results shows that the 1∶2-Ag3PO4/HAP catalyst exhibited the best performance,achieving 50%degradation in 10 min and complete degradation in 40 min.The 1∶2-Ag3PO4/HAP catalyst was a highly efficient composite photocatalyst.
