中文摘要：以固体废弃物牡蛎壳为原料,利用水热法制备出高纯度的纳米羟基磷灰石(HAP),负载磷酸银(Ag_(3)PO_(4))制备出具有高效光催化性能的HAP/Ag_(3)PO_(4)纳米复合物。采用FT-IR、XPS、XRD和SEM对其晶型、化学结构和形貌进行了表征,证实Ag_(3)PO_(4)被成功负载在源于牡蛎壳的HAP上。在此基础上研究了HAP/Ag_(3)PO_(4)纳米复合物在水污染治理领域的应用,发现模拟日光照射4 min、纳米复合物用量为1.5 g/L、对初始质量浓度为20 mg/L的罗丹明B溶液的降解率达到94.2%,表明制备的HAP/Ag_(3)PO_(4)纳米复合物是一种高效光催化剂,可以快速高效地降解水中的有机污染物。

外文摘要：Using oyster shells as raw material,high-purity nano-hydroxyapatite(HAP)was prepared by hydrothermal method,and silver phosphate was loaded to prepare HAP/Ag_(3)PO_(4)nanocomposites with high photocatalytic performance.The crystal form,chemical structure and morphology were characterized by FT-IR,XPS,XRD and SEM.It was confirmed that silver phosphate was successfully loaded on HAP from oyster shells.On this basis,the application of HAP/Ag_(3)PO_(4)nanocomposites in the field of water pollution treatment was studied.It was found that the degradation rate of rhodamine B solution with initial mass concentration of 20 mg/L reached 94.2%with simulated sunlight for 4 min and dosage of nanocomposites of 1.5 g/L.It showed that the prepared HAP/Ag_(3)PO_(4)nanocomposite was a highly efficient photocatalyst,which can rapidly and efficiently degrade organic pollutants in water.
