The equilibrated catalyst ink is then dried under the wet-drying regime to obtain statistically representative microstructures. We also proposed a method to voxelise the resulting microstructures into segmented images, which can then be characterised using image analysis functions typically applied on tomographic datasets. The resulting statistical descriptors were then discussed to explain the representative nature of the simulation methodology and robustness of the workflow. This work has been reported as a proof of concept to develop a model that explains the complex aggregation phenomena observed in the manufacture of CLs.
