| description | <p dir="ltr">Catalytic methane decomposition (CMD) offers an eco-friendly method to produce COx-free hydrogen and solid carbon. An innovative approach for catalyst regeneration involves utilizing CO<sub>2</sub> as a reactant to produce CO via the Reverse Boudouard Reaction, which serves as a valuable feedstock for various chemicals and fuels. This study aims to investigate the role and interaction of Ni nanoparticles on cerium oxide support by comparing two catalysts: one synthesized via the conventional impregnation method (<i>Imp</i>) and the other through solution combustion synthesis (<i>SCS</i>). Both catalysts containing the same Ni loading of 5 wt% and were tested under identical conditions. Comprehensive characterization techniques, including XRD, H<sub>2</sub> and O<sub>2</sub> TPR, TEM, SEM, XPS, and Raman spectroscopy, were employed to elucidate the observed performances. The <i>SCS</i> catalyst resulted in smaller Ni nanoparticles with stronger metal-support interaction. Observations revealed both tip and base carbon growth for the <i>SCS</i> catalyst, whereas the <i>Imp</i> catalyst predominantly characterized by tip growth. For the <i>SCS</i> catalyst, carbon nanofibers and nanotubes were observed, and both appeared active in carbon CO<sub>2</sub> gasification. For the <i>Imp</i> catalyst, more crystalline carbon is observed. The amount of carbon produced was much more and managed to cover the entire catalyst. For <i>SCS</i> carbon coverage was partial. Two rates of CO<sub>2</sub> gasification were observed depending on the extent of carbon coverage. Across all tested temperatures and space velocities, the catalyst prepared by impregnation exhibited higher reaction rates. The <i>Imp</i> catalyst demonstrated 15 % higher CMD and 29 % more generated carbon than <i>SCS</i>. This work demonstrated the critical role of key factors influencing the catalytic performance of this cyclic process. This includes the Ni nanoparticle size and distribution, the metal-support interaction's strength, and the graphitic carbon's nature.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Environmental Chemical Engineering<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.jece.2024.114496" target="_blank">https://dx.doi.org/10.1016/j.jece.2024.114496</a></p> |
