| Abstract(E) | We calculated diffusion coefficients for porous ternary catalysts composed of nanoscale particle aggregates featuring submicron-scale interconnected pores using diffusion simulations. These coefficients were subsequently incorporated into a particle-layer model as a simplified representation of the porous structure. By conducting a comprehensive analysis integrating flow, diffusion, and reaction processes, we elucidated the combined effects of the interconnected pore network and particle stacking structure on the overall reaction rate. |
