Mesopores in USY Zeolites [PDF]
, 2010 International audienceZeolites of type NaY synthesized by use of seed-solution and zeolite X-seeds to initialise the crystallization were compared. A different homogeneity of the internal framework structure related to the Si/Al ratio was expected. Thus,

Acid and steric synergies in industrial Y zeolites for 9, 10-dihydroanthracene hydrocracking
Catalysis Communications, 2023 In the hydrocracking of 9, 10-dihydroanthracene, acid sites and their locations in the Y zeolites play crucial roles. Hydrogen transfer is the dominant reaction for the industrial Y zeolites with undeveloped mesopores whether at low or high temperatures.

A review on the role of hierarchical zeolites in the production of transportation fuels through catalytic fast pyrolysis of biomass [PDF]
Biofuel Research Journal, 2020 Design of highly active catalysts plays a critical role in catalytic fast pyrolysis (CFP) of lignocellulosic biomass. Advanced catalysts can improve the deoxygenation rate of pyrolysis vapors and boost the production of fuel precursors.

Coordination Chemistry in Zeolites
Journal of inclusion phenomena and molecular recognition in chemistry, 1995 Zeolites are relatively rigid inorganic matrices with cavities and channels of molecular dimensions and of different sizes and shapes. Transition metal ion (TMI) complexes in molecular sieves have three main characteristics: (1) the complexes have strongly reduced mobility with respect to their solution mobility and deactivating aggregations may be ...

Advanced Functional Materials, EarlyView.Methane photocatalytic activation under mild conditions remains a formidable challenge in the synthesis of solar fuels. In this review, we emphasize the growing importance of multifunctional materials and hybrid systems within a unified mechanistic framework that integrates selective C─H bond activation, formation and control of intermediates, C─C ...

The thermal dehydration of natural zeolites [PDF]
, 1974 The zeolites constitute a group of minerals of much interest from geological, mineralogical and technological points of view. Structurally, they are tectosilicates with an 'open' framework containing channels and cavities which accommodate cations and ...

Advanced Materials, EarlyView.This work reports a direct, biocompatible method to synthesize UiO‐66, enabling one‐step encapsulation of proteins without compromising crystallinity or activity. Using advanced in situ and ex situ techniques, the study reveals that proteins integrate concurrently with MOF growth, forming crystalline protein@UiO‐66 nanoparticles, and provide insight ...
