Observation of oxygen evolution over a{Ni12}-cluster-based metal-organic framework
文献摘要：
The development of efficient electrocatalysts based on non-noble metals for oxygen evolution reaction(OER)remains an important and challenging task.Multinuclear transition-metal clusters with high structural stability are promising OER catalysts but their catalytic role is poorly understood.Here we report the crystallographic observation of OER activity over robust{Ni12}-clusters immobilised in a porous metal-organic framework,NKU-100,by single-crystal X-ray diffraction as a function of external applied potential.We observed the aggregation of confined oxygen species around the{Ni12}-cluster as a function of applied potential during the electrocatalytic process.The refined occupancy of these oxygen species shows a strong correlation with the variation of current density.This study demonstrates that the enrichment of oxygen species in the secondary co-ordination sphere of multinuclear transition-metal clusters can promote the OER activity.
