This work presents an example of the design and manufacture capabilities that 3D printing can introduce in ca-talysis. A multi-purpose catalyst, with fast heat and mass transfer and low-pressure drop has been designed andmanufactured by 3D printing. The novelty of the methodology is the combination of advanced techniques for ac-curate control on the micropore-level allied with a generic framework for the design of macropore and structurallevels. The ability to design ordered macroporous should be combined with adequate and controllable implanta-tion of surface functionalities. With this combination of advanced techniques for macroand micro-pore control, itis possible to produce catalysts that unlock traditional trade-off compromises between diffusion, pressure dropand heat transfer.To demonstrate this novel methodology, we have designed and 3D printed a cubic iso-reticular foam inAlSi10Mg. After producing the support, its entire internal area was anodized to high-surface alumina followedby Pt deposition. We have verified the reproducibility of this technique by manufacturing a catalyst for a demon-stratorwith 8 m length. The test reactionwas oxidation ofNO toNO2with themainaim to accelerate thisreactionfor additional recovery of energy in the production of nitric acid.
