The pore structure of a simulated washcoat layer was evaluated using the Mean Transport Pore Model (MTPM). The MTPM provides the mean diffusive pore radius (rm) of a simulated washcoat layer from the experimentally measured effective diffusion coefficient (De). However, data previously published in the literature indicated that the value of rm depended on the choice of diffusive gas for the measurement of De. Therefore, a new, more efficient method was developed to estimate rm. To obtain base… Expand
