摘要

在分子筛咪唑盐框架(ZIFs) ZIF-11和ZIF-12中分别包封[Ru(bpy) 3] 2+,制备了Ru(bpy) 3 @ZIF-11和Ru(bpy) 3 @ZIF-12催化剂(bpy = 2,2′‐联吡啶),并比较了它们的光催化活性。通过x -射线衍射分析和紫外-可见吸收光谱法对其晶体形态和光催化活性进行了表征。[Ru(bpy) 3] 2+ @ZIF-12催化剂具有优异的光催化稳定性,在Ru(bpy) 3 @ZIF-12复合材料中表现出[Ru(bpy) 3] 2+和Co的协同作用,并且电子从[Ru(bpy) 3] 2+部分高效地转移到ZIF- 11框架中。

Enhancement of Photocatalytic Activity of Tris (bipyridine) Ruthenium by Encapsulation in Zeolitic Imidazolate Framework-11 and 12
In this study, Ru(bpy) 3 @ZIF-11 and Ru(bpy) 3 @ZIF-12 catalysts (bpy = 2,2 ′ ‐bipyridine) were synthesized by encapsulating [Ru(bpy) 3 ] 2+ in zeolitic imidazolate frameworks (ZIFs) ZIF-11 and ZIF-12, respectively, and their photocatalytic activities were compared. Samples of different composites were prepared from their powders, and their crystal morphologies and photocatalytic activities were evaluated by X-ray diffraction analysis and UV-visible absorption spectrometry. [Ru(bpy) 3 ] 2+ @ZIF-12 catalysts possessed excellent photocatalytic stability and exhibited a synergistic effect of [Ru(bpy) 3 ] 2+ and Co in the Ru(bpy) 3 @ZIF-12 composite, and efficient electron transfer from the [Ru(bpy) 3 ] 2+ moiety to the ZIF- 11 framework.
