巯基功能化的金属有机框架纳米粒子的合成及形貌调控
|
Abstract:
本文选择四氯化锆作为金属源，与含有巯基的配体2,5-对巯基对苯甲酸进行配位，利用溶剂热的方法合成了具有纳米尺度的金属有机框架纳米粒子(UiO-66-SH)。通过改变反应物浓度、反应时间以及反应温度等条件实现了对UiO-66-SH纳米粒子的尺寸和形貌的调控。进一步利用SEM、IR、XRD等对其形貌、组成和结构进行了详细的表征。此外，由于所合成的UiO-66-SH结构中含有巯基功能团，可以被广泛应用于污水中重金属离子的吸附去除。
In this work, nanoscale metal-organic framework nanoparticles were synthesized by solvothermal method using zirconium tetrachloride as a metal source and coordinating with the sulfhydryl groups contained organic ligand of 2,5-dimercaptoterephthalic acid. The size and morphology of UiO-66-SH nanoparticles can be controlled by changing the reactant concentration, reaction time, and reaction temperature. The morphology, composition and structure were further characterized in detail using SEM, IR and XRD. In addition, due to the sulfhydryl functional groups in the synthesized UiO-66-SH structure, it can be widely used for the adsorptive removal of heavy metal ions from wastewater.
