This presentation will highlight new developments in the design and assembly of MOF-supported heterogeneous catalysts. The presentation will touch on design principles and illustrate via a few case studies how transition-metal based catalysts can be reproducibly installed on uniform arrays of ultrasmall metal-oxide supports. In the presented examples the supports double as crystallographically well-defined nodes for thermally and chemically robust metal-organic frameworks. Precise structural characterization serves to power a virtuous cycle of mechanistic refinement and performance optimization via consecutively coupled experimental and theoretical (computational) investigations of catalyst functional behavior. Examples will focus on engendering selectivity in gas-phase reactions involving small hydrocarbons, electrocatalytically converting substrates like CO<sub>2</sub> to higher alcohols, and/or systematically tuning photocatalytic activity for water splitting. Finally, the presentation will touch on the use of synchrotron-based X-ray methods for validating catalyst structures, in concluding under <i>operando</i> conditions.
