Abstract
Hierarchical zeolites have been demonstrated to be advantageous in catalysis and adsorption applications due to facilitated diffusion without degrading its molecule sieving function. However, the direct synthesis of hierarchical zeolites in one step is still challenging. Herein, we report a simple one-step synthesis of single-crystalline hierarchical zeolites by fractal growth induced by the strong adsorption of heteroatom metal species on the initially formed crystals. This method is feasible in the presence of a variety of metal species (M–OH), which can develop a stronger hydrogen bond with Si–OH in comparison to that among Si–OH themselves, such as Ti, Sn, Ga, Nb, and V. Furthermore, the method is versatile as substantiated with several common zeolites, including ZSM-5, TS-1, and ZSM-11. Such a hierarchical zeolite exhibits significantly enhanced activity in polyethylene pyrolysis and a remarkably prolonged lifetime in methanol conversion to hydrocarbons due to facilitated diffusion.
期刊介绍：
The journal Chemistry of Materials focuses on publishing original research at the intersection of materials science and chemistry. The studies published in the journal involve chemistry as a prominent component and explore topics such as the design, synthesis, characterization, processing, understanding, and application of functional or potentially functional materials. The journal covers various areas of interest, including inorganic and organic solid-state chemistry, nanomaterials, biomaterials, thin films and polymers, and composite/hybrid materials. The journal particularly seeks papers that highlight the creation or development of innovative materials with novel optical, electrical, magnetic, catalytic, or mechanical properties. It is essential that manuscripts on these topics have a primary focus on the chemistry of materials and represent a significant advancement compared to prior research. Before external reviews are sought, submitted manuscripts undergo a review process by a minimum of two editors to ensure their appropriateness for the journal and the presence of sufficient evidence of a significant advance that will be of broad interest to the materials chemistry community.
