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 ...

Boosting Electron‐Hole Charge Separation in CO2 Photoreduction through Fluoroporphyrin‐Linked Nickel(II)‐Acetylide Frameworks

open access: yesCarbon Energy, EarlyView.
A NiII‐acetylide framework, H2TFPP‐Ni‐AF, demonstrates outstanding photocatalytic CO2 reduction performance: 13.16 mmol h−1 g−1 of CO with 97.9% selectivity. Synergistic interactions, including d‐p orbital hybridization within NiII‐bis(acetylide) moieties ( − C ≡ C−NiII(PBu3)2 − C ≡ C − ) and the efficient charge transport afforded by π‐conjugated ...

Superior CO2 Conversion Performance by Er‐Doped BiOCl Nanosheets Through Synergistic Photocatalytic Memory Effect and Er‐Doping

open access: yesCarbon Energy, EarlyView.
Er‐doping and the photocatalytic memory effect through visible‐light irradiation synergistically reconstruct internal electronic states of ultrathin Er‐doped BiOCl nanosheets and generate stable oxygen vacancies. Light absorption, charge carrier separation, and CO2 adsorption capability are subsequently enhanced, leading to a significant increase in ...

Biomass‐Coupled HER System: A Strategy for Sustainable and Low‐Cost Hydrogen Production

open access: yesCarbon Energy, EarlyView.
Pine wood is carbonized into a hierarchically porous biochar anode that undergoes carbon oxidation reaction, replacing the oxygen evolution reaction in alkaline water electrolysis. The resulting biomass‐coupled HER system converts water into hydrogen at low cell voltages, enabling low‐cost H2 production from renewable carbon resources. ABSTRACT Biomass‐

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‐
