Abstract (EN): To demonstrate for the first time the potential of stereolithography-printed, architected, bio-based carbon-supported Ni catalysts for CO(2 )methanation, three honeycomb carbon structures with different textural properties were prepared, impregnated with 15 wt.% of nickel metal particles, and studied to correlate their catalytic performances with their textural properties and surface chemistry. Compared with the non-activated monolith and the steam-activated monolith, the CO2-activated monolith achieved a higher CO2 conversion of 62 % with a CH4 selectivity of 73 % at 460 degrees C. Our comparative study demonstrated that the CO2-activated carbon support, although having fewer basic sites on the surface, exhibits greater dispersion of the Ni phase, enabling an increase in H2 chemisorption. These results are of interest for further studies related to the optimization of catalytic performance through the design of the architectural and textural properties of such macrostructures.
