摘要
利用毛蚶（Anadara granosa）壳作为生物钙源，通过原位共沉淀和水热法制备了羟基磷灰石支撑的 Ag3PO4（Ag3PO4/HA）纳米复合材料。所获得的纳米复合材料通过不同的仪器分析进行了表征。X 射线衍射光谱、透射电子显微镜和 X 射线光电子能谱分析证实，在 HA 结构上形成了分散的 Ag3PO4，颗粒大小为 10-40 纳米。该材料的带隙能为 2.3 eV，支持其作为光催化剂降解罗丹明 B 的活性。该纳米复合材料在处理 120 分钟后的去除率达到 99.87%，并且在 5 个循环中的去除率和动力学常数变化不大，证明了其可重复使用性。该纳米复合材料对大肠杆菌、金黄色葡萄球菌、肺炎双球菌和化脓性链球菌具有抗菌活性。
In-situ synthesis of hydroxyapatite-supported Ag3PO4 using cockle (Anadara granosa) shell as photocatalyst in rhodamine B photodegradation and antibacterial agent
A nanocomposite of hydroxyapatite-supported Ag3PO4 (Ag3PO4/HA) was prepared by in-situ co-precipitation followed by hydrothermal method by utilizing cockle (Anadara granosa) shell as biogenic calcium source. The obtained nanocomposite was characterized by different instrumental analyses. X-ray diffraction spectroscopy, transmission electron microscopy, and X-ray photoelectron spectroscopy analyses confirmed the formation of dispersed Ag3PO4 on HA structure with the particles size ranging at 10–40 nm. The material has band gap energy of 2.3 eV which support the activity as photocatalyst for rhodamine B degradation. The removal efficiency of 99.87% was expressed by the nanocomposite for 120 min of treatment, and reusability was demonstrated by insignificant change of the removal and kinetics constant for 5 cycles. The nanocomposite showed antibacterial activity against E. Coli, S. aureus, K. Pneumonia, and S. pyogenes.
