| 摘 要： | 以镍铝摩尔比为3∶1,尿素作为沉淀剂,采用均匀沉淀法制备了Ni2+-Al3+-CO2-3-LDHs层状材料。以Ni2+-Al3+-CO2-3-LDHs作为前驱体,分别与NaCl、钼酸钠( Na2 MoO4·2H2 O)进行离子交换反应,成功构建了Ni2+-Al3+-MoO2-4-LDHs防腐缓蚀剂。通过XRD、SEM、FT-IR、TG-DTG、ICP对样品进行了分析表征,研究结果表明MoO2-4插入LDHs层间,其层间距由0.769 nm增加到0.982 nm,样品晶相完整,并保持了良好的层状结构。

| Abstract: | Using carbamide as precipitant, Ni2+-Al3+-CO2-3 -LDHs was prepared by homogeneous precipitation method when the Ni/Al molar ratis was 3∶1. Then the corrosion inhibitor of Ni2+-Al3+-MoO2-4 -LDHs was successfully constructed through ion exchange with NaCl and Na2 MoO4 · 2H2 O respectively using Ni2+-Al3+-CO2-3 -LDHs as precursor. The synthesized Ni2+-Al3+-MoO2-4 -LDHs were characterized by XRD, SEM, FT-IR, TG-DTG and ICP. The experimental results show that the basal spacing of the LDHs increases from 0. 769 nm to 0. 982 nm when the MoO2-4 anions insert to the layer space of Ni2+-Al3+-LDHs, which show well-crystalline structure and layered feature. |
