Organic catalysis over zeolites: A perspective on reaction paths within micropores
TL;DR: A broad classification and survey of organic chemistry over zeolites is presented in this paper, which reflects, for the most part, a mechanistic rather than a process or applications frame of reference.

Surface curvature effects in physisorption and catalysis by microporous solids and molecular sieves
TL;DR: In this paper, a van der Waals model for the interaction energy and the sticking force of a molecule lodging in a pore is used to rationalize semiquantitatively a number of well-accepted observations, e.g., the role of zeolites as molecular traps, the origin of the surface barrier postulated to reconcile the large divergence between intracrystalline (self-diffusion) and macroscopically measured (nonequilibrium) diffusion coefficients; the rapid diffusion of molecules in tight-fitting zeolite pores; the window effect observed for

Anomalous crystallization mechanism in the synthesis of nanocrystalline ZSM-5
TL;DR: In this paper, a nanocrystalline ZSM-5 (crystal size in the range 10-100 nm) has been synthesized in only 24 h by hydrothermal crystallization of clear supersaturated homogeneous synthesis mixtures.

Chapter 16 “Zeolites in Organic Syntheses”
TL;DR: In this article, the authors discuss that the size of the molecules to be converted or synthesized seems limited by the pore dimensions of zeolites, however, a growing number of examples related to outer surface catalysis, or to selective scavenging of side products or impurities or to slow release of reagents explains that zeolite can be of much value also in the synthesis or conversion of large molecules or materials.

A seed surface crystallization approach for rapid synthesis of submicron ZSM-5 zeolite with controllable crystal size and morphology
TL;DR: In this paper, a method based on seed surface crystallization (SSC) mechanism has been proposed for facile, rapid, controllable and low-cost synthesis of ZSM-5 zeolite with submicron-size and interesting core-shell structure.

Selective alkylation of toluene with methanol to produce para-xylene
TL;DR: In this paper, a controlled reduction in the effective dimensions of the catalyst pore openings, and/or channels, along with deactivation of acidic surface sites, has been proposed as a mechanism for the selective production of p-xylene.

Molecular shape selective catalysis
TL;DR: In this article, the authors proposed a method for shape selective catalysis in the intracrystalline space of siliceous zeolites, using diffusional mass transport dynamics and steric modification of the intrinsic reaction rates.

A mathematical theory of enhanced para-xylene selectivity in molecular sieve catalysts
TL;DR: In this article, a mathematical theory is developed to explain the enhancement of para-selectivity and the decline of selectivity under increasing conversion in certain molecular sieve catalysts, such as the zeolite ZSM-5.
