Post‐Shaping Over‐Impregnation: A Facile Strategy for Pt‐KL Catalysts With Ultrahigh Metal Dispersion and Enhanced Aromatization Performance

Carbon and Hydrogen, EarlyView.
A scalable post‐shaping strategy achieves precise Pt localization within KL zeolite, where optimized spatial distribution minimizes diffusion barriers to deliver superior n‐hexane aromatization activity, selectivity, and stability. ABSTRACT The precise localization of metal clusters within zeolite frameworks is critical for the aromatization catalysis.

Unlocking Enhanced Hydrogen Storage in Naphthalene via K‐Induced Acidity and Metal Dispersion in Dendritic Catalysts

Carbon and Hydrogen, EarlyView.
Dendritic micro‐mesoporous composite catalysts through K‐induced enhancement of acidity and metal dispersion were developed. ABSTRACT Novel dendritic ZSM‐22/DMSNs (ZD) micro‐mesoporous composites with center–radial pore structure and suitable acidity were developed by nano‐assembly strategy. Subsequently, Pt/ZD‐K catalysts were synthesized based on the

The Investigation of the Deactivation of the Metal‐Modified ZSM‐5 Zeolites for the Catalytic Dehydration of Glycerol

Carbon and Hydrogen, EarlyView.
During the glycerol dehydration over ZSM‐5 zeolite, the modification by metal promoters results in the suppression of the bicyclic and tricyclic aromatics over the modified ZSM‐5 zeolite catalysts. However, the issue of the fast deactivation still remains an apparent challenge, which requires more different perspectives to understand the deactivation ...

Grafting Nanolayers of Ni and Co Catalysts Around the Edges of Hierarchical Zeolite 13X by Leveraging the Crystal's Defects for CO2 Methanation

Carbon Energy, EarlyView.
The deactivation of nickel‐based catalysts at high temperatures poses a significant challenge in CO2 methanation processes. To address this, a strong metal–support interaction between nickel and the support was engineered by exploiting the crystal defects present in hierarchical porous zeolite 13X.
