摘要:
以4,4’-二咪唑亚甲基联苯(BBPTZ), 4-硝基苯甲酸 (p-NBH) 和1, 3,5-三咪唑亚甲基苯 (TIMB) 为配体,通过水热法分别合成了配合物 1{[Zn2(p-NBH)4 (BBPTZ)2]·H2O}n、2 [Zn3(TIMB)2Cl2n。利用傅里叶变换红外光谱、X-射线单晶衍射、热重分析、价带-X射线光电子能谱、紫外-可见漫反射光谱等技术对配合物的结构与性质进行了表征。单晶衍射结果显示配合物 1、 2 均属于三斜晶系 P-1 空间群,且均具有三维空间构型。为进一步研究金属有机框架(MOFs)在光催化领域的应用,将这两种 MOFs 作为光催化剂在紫外光下降解亚甲基蓝,并研究了催化剂用量、体系酸碱度等因素对其光催化性能的影响。结果表明:两种MOFs 材料在紫外光下均对亚甲基蓝表现出良好的光催化降解活性和稳定性,在碱性条件下其光降解效率提升明显。本研究为 MOFs 基光催化剂的设计提供了新的思路。
Abstract:
Using 4, 4’-diimidazole methylene biphenyl (BBPTZ),4-nitrobenzoic acid (p-NBH) and 1, 3, 5-tri(1-imidazolyl) methylene benzene (TIMB) as ligands, two new complexes 1{[Zn2(p-NBH)4 (BBPTZ)2]·H2O}n and 2 [Zn3(TIMB)2Cl2]n were synthesized by hydrothermal method, respectively. The structure and properties of the complexes were characterized by Fourier transform infrared spectroscopy,X- ray single crystal diffraction,thermogravimetric analysis,X-ray photoelectron spectroscopy and UV-vis diffuse reflectance spectroscopy. Single crystal diffraction results showed that complexes 1 and 2 belong to the triclinic P-1 space group and have three-dimensional space configuration. To study the application of metal-organic frameworks (MOFs) in photocatalysis,two kinds of MOFs were used as photocatalyst to degrade methylene blue solution under ultraviolet light. The effects of catalyst dosage and pH of the system on the photocatalytic performance were also studied. The results indicated that two kinds of MOFs materials exhibit good photocatalytic activities and strong stability in methylene blue degradation. The photocatalytic efficiency is obviously improved under alkaline conditions. This study provides new ideas for the design of MOFs-based photocatalysts.
