Journal ArticleDOI
From Microporous to Mesoporous Molecular-Sieve Materials and Their Use in Catalysis
TL;DR: Corma et al. as mentioned in this paper used the Dupont Award on new materials (1995), and the Spanish National Award “Leonardo Torres Quevedo” on Technology Research (1996) on technology research (1996), to recognize the performance of zeolites as catalysts for oil refining and petrochemistry.

Stable single-unit-cell nanosheets of zeolite MFI as active and long-lived catalysts
Minkee Choi,Kyungsu Na,Jeongnam Kim,Jeongnam Kim,Yasuhiro Sakamoto,Yasuhiro Sakamoto,Osamu Terasaki,Osamu Terasaki,Ryong Ryoo,Ryong Ryoo +9 more
TL;DR: It is shown that appropriately designed bifunctional surfactants can direct the formation of zeolite structures on the mesoporous and microporous length scales simultaneously and thus yield MFI (ZSM-5, one of the most important catalysts in the petrochemical industry) zeolites that are only 2 nm thick, which corresponds to the b-axis dimension of a single MFI unit cell.

Surfactant Control of Phases in the Synthesis of Mesoporous Silica-Based Materials
TL;DR: In this article, the molecular shapes of covalent organosilanes, quaternary ammonium surfactants, and mixed surfactant in various reaction conditions can be used to synthesize silica-based mesophase configurations.

Amphiphilic organosilane-directed synthesis of crystalline zeolite with tunable mesoporosity
Minkee Choi,Hae Sung Cho,Rajendra Srivastava,Chithravel Venkatesan,Dae-Heung Choi,Ryong Ryoo +5 more
TL;DR: The synthesis of the crystalline aluminosilicate materials with tunable mesoporosity and strong acidity has potentially important technological implications for catalytic reactions of large molecules, whereas conventional mesoporous materials lack hydrothermal stability and acidity.
