Aperture-opening events were used to encapsulate molecular ruthenium complexes in the metal-organic framework UiO-66. By taking advantage of the solvent-dependency of linker exchange reactions, the encapsulated complexes [Ru]@UiO-66 could be used as catalysts for the hydrogenation of carbon dioxide with little evidence for catalyst leaching. These catalysts demonstrated properties that were hybrid between homogeneous and heterogeneous catalysts. Unlike many heterogeneous catalysts, [Ru]@UiO-66 was highly selective for the formation of formic acid. Unlike most homogeneous catalysts, [Ru]@UiO-66 could be recycled without at least five times without loss in activity. Moreover, [Ru]@UiO-66 was less prone to catalyst poisoning compared to either homogenous analogs or ruthenium complexes adsorbed to UiO-66. Mechanistic insights into the encapsulation process as well as using the new catalyst constructs for advanced applications in catalysis will be discussed.
