On page 164, Pérez-Ramírez et al. demonstrate that partial detemplation followed by desilication in alkaline media is a powerful and elegant approach for the design of hierarchical zeolites with a tailored degree of mesoporosity. This achievement, illustrated for large beta crystals, is based on the distinct capability of NaOH to extract silicon in template-containing or template-free regions of the zeolite. The introduced mesoporosity enhances the effectiveness of the materials in catalysis due to shorter diffusion lengths.
