The engineering of metal-organic frameworks (MOFs) into membranes and films is being investigated, to transform laboratory-synthesized MOFs into industrially viable products for a range of attractive applications. However, rational design and construction of highly permeable MOF thin films, without trade-offs in terms of structural mechanical stability, remains a significant challenge. Herein, a simple, general strategy is reported to prepare thin MOF nanosheet (NS)-assembled frame film via heteroepitaxial growth from metal hydroxide film. As the thin MOF NS-assembled film significantly enhances the permeability of mass though the film, the resultant gold nanoparticle (Au NP)@MOF film exhibits much higher catalytic efficiency than the Au NP@MOF bulk film. Meanwhile, the unique framework of the MOF NS-assembled film resists torsion and collapse, so the composite catalyst exhibits long-term stability.
