Abstract
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.
