Co₃O₄@SiO₂ 3D Monolith Catalysts, Additive Manufactured Structures for Propane Oxidation Reaction

In this study, we successfully fabricated a three‐dimensional Co 3 O 4 @SiO 2 3D Monolith catalyst. This process allowed for the effective and straightforward anchoring of Co 3 O 4 nanoparticles onto SiO 2 3D Monoliths. The active Co 3 O 4 phase was primarily identified through XRD and XPS analyses, complemented by Co 3 O 4 loading measurements (1.7 %). This innovative catalyst displayed remarkable proficiency in selectively converting propane to carbon dioxide. Additionally, it was demonstrated that the catalytic activity remained unimpaired even upon the catalyst's reuse in 5 successive reaction cycles. This performance was observed across various heating ramps, showcasing the catalyst's stability over time.
