摘要

摘要采用溶剂热法合成了二维铀酰有机骨架(UOF) UO2(L)(DMA) (1) (H2L = 2-氨基间苯二甲酸，DMA = N, N-二甲基乙酰胺)，并用元素分析、红外光谱、单晶x射线衍射、固体荧光、粉末x射线衍射、热重分析和紫外可见光谱对其进行了表征。在可见光照射下，UOF 1对有机染料亚甲基蓝(MB)和罗丹明B (RhB)的降解效率分别为93.2和86.5%，表明UOF 1具有显著的光催化活性。UOF 1对MB和RhB的混合染料也有一定的选择性。

Synthesis, structure, and photocatalytic properties of a two-dimensional uranyl organic framework

Abstract A two-dimensional uranyl organic framework (UOF) UO2(L)(DMA) (1) (H2L = 2-aminoisophthalic acid, DMA = N, N-dimethylacetamide) has been solvothermally synthesized and characterized thoroughly by elemental analysis, infrared spectroscopy, single-crystal X-ray diffraction, solid fluorescence, powder X-ray diffraction, thermogravimetric analysis, and UV–visible spectroscopy. Furthermore, the degradation efficiencies of UOF 1 to organic dye methylene blue (MB) and rhodamine B (RhB) are 93.2 and 86.5% under irradiation of visible light which indicates that UOF 1 has remarkable photocatalytic activity. UOF 1 also displayed a certain selectivity for mixed dyes of MB & RhB.

期刊介绍： Zeitschrift für Kristallographie – Crystalline Materials was founded in 1877 by Paul von Groth and is today one of the world’s oldest scientific journals. It offers a place for researchers to present results of their theoretical experimental crystallographic studies. The journal presents significant results on structures and on properties of organic/inorganic substances with crystalline character, periodically ordered, modulated or quasicrystalline on static and dynamic phenomena applying the various methods of diffraction, spectroscopy and microscopy.
