Photochemistry of Organic Molecules Within Zeolites: Role of Cations
Photochemistry in organized media has attracted considerable attention during the last decade [1]. A number of materials have been utilized to “hold” molecules in a fixed orientation so as to initiate reactions.

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 ...

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.

Second-Sphere Effects on Methane Hydroxylation in Cu-Zeolites
, 2018 Two [Cu2O]2+ cores have been identified as the active sites of low temperature methane hydroxylation in the zeolite Cu-MOR. These cores have similar geometric and electronic structures, yet different reactivity with CH4: one reacts with a much lower ...

Porous Carbon Materials for Carbon Dioxide Capture
Carbon Energy, EarlyView.This work aims to address the current status and challenges associated with the regulation of pore structures, as well as the influence of pore structures on CO2 capture. Systematic quantitative analysis of structure–property relationships, combined with machine learning approaches, can effectively evaluate the contributions of structural ...
