Abstract

A cobaloxime H evolution catalyst with a hydroxo-functionalized pyridine ligand, Co(dmgH)(4-HEP)Cl [dmgH = dimethylglyoxime, 4-HEP = 4-(2-hydroxyethyl)pyridine] was immobilized on a chromium terephthalate metal-organic framework (MOF), MIL-101(Cr), to construct a MOF-catalyst hybrid which displays good photocatalytic H evolution activity. The longevity of the cobaloxime catalyst is increased by MOF incorporation, but limited by the stability of the cobalt-pyridine bond under turnover conditions.

摘要

一种带有羟基官能化吡啶配体的钴肟氢析出催化剂Co(dmgH)(4-HEP)Cl [dmgH = 二甲基乙二肟，4-HEP = 4-(2-羟乙基)吡啶] 被固定在对苯二甲酸铬金属有机框架（MOF）MIL-101(Cr)上，以构建一种表现出良好光催化析氢活性的MOF-催化剂杂化体。通过引入MOF，钴肟催化剂的寿命得以延长，但受周转条件下钴-吡啶键稳定性的限制。
