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.

KI‐Doped α‐Mo2C Stably Catalyze Near‐Equilibrium CO2 to CO Beyond 1000 Hours

open access: yesCarbon Energy, EarlyView.
Through iodine doping and effective stabilization of surface oxygen content, KI‐doped α‐Mo2C achieves a sustained equilibrium yield ratio of 0.95 over 1000 h at 400°C and 4 bar in reverse water–gas shift (RWGS) reaction. Furthermore, the catalyst has been successfully scaled up to the kilogram level, indicating considerable potential for industrial ...

Hydrogen Migration Enhances Proton‐Coupled Electron Transfer in an S‐Scheme Heterojunction for High‐Efficiency Photocatalysis

open access: yesCarbon Energy, EarlyView.
Precisely directed built‐in electric field in an S‐scheme heterojunction synergizes photogenerated charge separation with interfacial proton migration, thus co‐localizing electrons and protons on the NOH surface and boosting proton‐coupled electron transfer kinetics in the rate‐determining hydrogen release step. ABSTRACT The kinetic bottleneck in solar‐

Pressure‐Enhanced CO2‐to‐CO Electroreduction on Ag‐Based Catalysts: Industrially Relevant Rates and Mechanistic Insights

open access: yesCarbon Energy, EarlyView.
Ag‐based catalysts operated under elevated CO2 pressures exhibit markedly enhanced intrinsic activity for CO formation, with OD‐Ag achieving −200 mA cm–2 and 90% FECO at −1.3 VRHE. Mechanistic analysis shows that high pressure strengthens a *COOH‐mediated pathway by increasing intermediate coverage and suppressing hydrogen evolution, establishing CO2 ...
