Abstract

The molecular water oxidation catalyst [Ru(bda)(L)2] has been incorporated into pyridine-decorated MIL-101(Cr) metal-organic frameworks. The resulting MIL-101@Ru materials exhibit turnover frequencies (TOFs) up to ten times higher compared to the homogenous reference. An unusual dependence of the formal TOFs on oxidant concentration is observed that ultimately arises from differing amounts of catalysts in the MOF crystals being active.

摘要

分子水氧化催化剂[Ru(bda)(L)2]已被掺入吡啶修饰的 MIL-101(Cr)金属有机骨架中。与均相参比物相比，所得的 MIL-101@Ru 材料的周转频率（TOF）高出十倍。观察到异常的形式 TOF 对氧化剂浓度的依赖性，这最终源于 MOF 晶体中活性催化剂的数量不同。
