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

open access: yesCarbon 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

Investigating the early age crack resistance of concrete treated with silane-modified zeolite powder

open access: yesAlexandria Engineering Journal
This study investigates the efficacy of silane-modified zeolite powder in enhancing the early age crack resistance of concrete. Three concrete mixes were evaluated: a reference mix, a 20 % zeolite replacement mix, and a silane-modified zeolite mix.

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

open access: yesCarbon 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

open access: yesCarbon 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.
