Well‐Defined Metal–Organic‐Framework Hollow Nanostructures for Catalytic Reactions Involving Gases

Abstract

The miniaturization of metal–organic‐framework (MOF) crystals to the nanoscale brings enhanced or novel properties and fulfils specific application needs. The focus here is on a kind of nanoMOF with special configurations and outstanding properties – the hollow structure. Firstly recent advances on the synthesis of MOF hollow nanostructures are introduced. Then, a novel approach based on a heterometallic system is highlighted, by which the facile synthesis of well‐defined hollow MOF structures with high complexity is achieved. Moreover, MOF hollow nanostructures are emphasized as hosts/shell materials to incorporate functional catalysts that show dramatically enhanced performances in gas‐involved reactions due to their inherent gas‐absorption/storage properties.
