Quantitative insight into the three‐dimensional morphology of complex zeolite Y mesopore networks was achieved by combining electron tomography and image processing. Properties could be studied that are not measurable by other techniques, such as the size distribution of the intact microporous domains. This has great relevance in descriptions of the molecular diffusion through zeolite crystals and, hence, catalytic activity and selectivity.
