摘要
本文利用快速沉淀法合成一类沸石咪唑骨架材料(zeolitic imidazolate frameworks, ZIFs),为一类由金属原子桥联多个咪唑类环型有机分子组成的化合物,具有易合成、高热稳定性和高化学稳定性的特点。利用X-射线粉末衍射仪(XRD)和红外光谱仪(FTIR)等表征手段,对ZIFs光催化剂进行物相分析。选用吸附孔雀石绿(MG)和亚甲基蓝(MB)作为探针反应,考察研究ZIFs的吸附性能。测试结果表明吸附60 min后,ZIF-8和ZIF-67对MG的吸附率高达100%。
In this paper, a typical metal organic freamwork material(MOFs), ZIFs has been synthesized through hydrothermal method. Their structures and properties are determined by the X-ray diffraction(XRD), Fourier transform infrared spectroscopy(FTIR), transmission electron microscopy(TEM). Adsorption of malachite green(MG) and methylene blue(MB) were employed as a model reaction to evaluate the adsorption capacity of the ZIFs. Experimental results have shown that after adsorption for 60 min almost 100 % MG has been adsorbed by ZIF-8 and ZIF-67.
