一种具有纳米笼结构的多酸基金属有机框架晶态材料及其制备方法和应用
摘要：
一种具有纳米笼结构的多酸基金属有机框架晶态材料及其制备方法和应用，它涉及一种具有纳米笼结构的金属-有机框架晶态材料。本发明的目的是要解决现有技术合成的纳米笼结构的POMOFs晶态材料的难度大和降解罗丹明B有机染料效果差的问题。一种具有纳米笼结构的多酸基金属有机框架晶态材料的化学式为Ag10(tta)4(H2O)4(SiWIV10WV2O40)，晶系为四方；空间群为I-4m2；α＝90°，β＝90°，γ＝90°，Z＝2。方法：将硅钨酸、硝酸银、四氮唑和矿化剂溶解到蒸馏水中，调节pH值，再在温度为160℃下反应3天。本发明可获得一种具有纳米笼结构的多酸基金属有机框架晶态材料。
摘要（英）：

The invention relates to a metal-organic framework crystalline material with a nano-cage structure, in particular to a polyoxometalate (POM)-based metal-organic frameworks (POMOFs) crystalline material with a nano-cage structure and a preparation method and application thereof and aims to solve the problems in the prior art that a POMOFs crystalline material with a nano-cage structure is high in synthesis difficulty and poor in rhodamine B organic dye degradation effect. The POMOFs crystalline material has the chemical formula of Ag10(tta)4(H2O)4(SiW10W2O40), the tetragonal system, and the space groups of I-4m2, alpha=90, beta=90, gamma=90 and Z=2. The preparation method comprises the following steps: dissolving silicotungstic acid, silver nitrate, tetrazole and a mineralizer in distilled water; regulating the pH value; carrying out a reaction for 3 days at 160 DEG C. The POMOFs crystalline material with the nano-cage structure can be obtained.
