| Abstract Scope |
This study examines the structure-property-performance relationships of Ni and Co ammonia decomposition catalysts through the use of a comprehensive array of ex-situ, in situ, and operando characterization techniques. X-ray Absorption Fine Structure (XAFS), X-ray Diffraction (XRD), and total scattering were utilized to analyze the structural variations introduced by disparate synthesis and processing methods across different length scales. These techniques facilitated the investigation of the impact of synthesis and processing conditions on the structural and functional properties of the catalysts. Our findings highlight the significant influence of minor structural variations on overall catalytic performance. Integrating in situ and operando studies provided real-time insights into the structural evolution of the catalysts under operational conditions, underscoring the critical role of multiscale characterization techniques in material design and optimization. This research emphasizes the necessity of multiple in-situ and operando techniques to accurately determine the structure-property-performance relationships and develop efficient catalysts for energy applications. |
