Understanding the Formation Mechanism of Metal Nanocrystal@MOF-74 Hybrids

Raffaella Buonsanti, Wendy Lee Queen, Anna Loiudice, Daniel Teav Sun

We report a one-step synthetic strategy to encapsulate copper nanocrystals (Cu NCs) in a carboxylate-based metal organic framework (MOF-74) to construct Cu@Cu-MOF-74 hybrids. One of the hurdles to realizing metal NC@MOF hybrids with uniform morphology and ...
