bioethanol hydrogen production catalytic reforming bimetallic catalysts nickel cerium oxide

The increasing demand for sustainable energy sources has directed significant research efforts towards the development of efficient catalysts for hydrogen production. This study addresses the catalytic reforming of bioethanol as a promising route to generate hydrogen. Our main objective was to explore novel catalytic systems that enhance the efficiency and selectivity of hydrogen production. We designed and synthesized a series of bimetallic catalysts, incorporating transition metals with rare earth elements, to analyze their performance in bioethanol steam reforming. Using advanced characterization techniques, including X-ray diffraction and electron microscopy, we evaluated the structural and surface properties of these catalysts. Our findings demonstrate that the catalyst composed of nickel and cerium oxide exhibited superior activity and stability, attributed to the enhanced dispersion of active sites and resistance to carbon deposition. These results indicate a viable pathway for the development of cost-effective and durable catalysts for industrial applications. The conclusions drawn from this research highlight the potential of optimizing metal combinations in catalysts to achieve higher hydrogen yields, presenting significant implications for the advancement of renewable energy technologies.
