Description
Summary:In this study, we successfully fabricated a three‐dimensional Co3O4@SiO2 3D Monolith catalyst. This process allowed for the effective and straightforward anchoring of Co3O4 nanoparticles onto SiO2 3D Monoliths. The active Co3O4 phase was primarily identified through XRD and XPS analyses, complemented by Co3O4 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. The paper describes the fabrication of Co3O4@SiO2 monoliths using a 3D extrusion plotter via additive manufacturing. Notably, these 3D structures, with just 1.7% cobalt loading, efficiently convert propane to CO2 and retain activity over five cycles, demonstrating superior performance compared to bare cobalt oxide. In Addition, this monoliths show stability across various reaction temperatures.
