TL;DR: The rational construction of pore models, especially hierarchical features, is highlighted with a careful classification from an industrial perspective accompanied by a detailed analysis of the theoretical mechanisms.

TL;DR: The spatial proximity between Bronsted acid sites (BAS) in HZSM-5 zeolites is demonstrated by 1 H double quantum (DQ) MAS NMR measurements as discussed by the authors.

TL;DR: A one-step synthesis method is described to prepare high-quality ultrafine inorganic semiconductor nanocrystals via a two-phase interface hydrolysis reaction under hydrothermal conditions and it is shown that the prepared nanocry crystals have good monodispersity and high crystallinity, as well as other related superior properties.

TL;DR: By employing Thiele modulus analysis in the cumene cracking reaction, it was found the effective diffusion length in hierarchical MFI zeolite was obviously shortened as discussed by the authors, which remarkably promoted accessibility to the internal surface and obviously improved the utilization of acid sites.

TL;DR: In this article, a careful steam treatment was used to produce pair-sites composed of a Lewis acid site, due to extra-framework Al species from the dealumination by steaming, and a Bronsted acid site due to bridging hydroxyl in the steamed HZSM-5 zeolites.
