Metal-organic frameworks (MOFs) are a class of versatile, highly porous materials whose structure and modifiable internal (pore)/external (surface) chemical environments make them amenable for a wide range of applications including gas storage and catalysis. [1] Recently, particle size has been shown to impact the physical and structural properties of MOFs; therefore careful consideration of the particle size and surface chemistry of MOFs must considered when examining a MOF for a specific application. [2] MOFs have been utilised for a number of heterogeneous catalytic pathways, but few studies have focused on the interplay of particle size and the surface chemistry of MOFs on their catalytic activity.

This contribution will present a recent project focused on surface catalysis with MOFs. Zeolitic imidazole framework (ZIF-8) has shown potential for Lewis acid/base surface-catalysed reactions, for example the Knoevenagel condensation and transesterifcation of triglycerides for the production of biodiesel. [3] The impact of particle size and morphology on the catalysis of a transesterification reaction at the surface of ZIF-8 will be discussed.
