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

Carbon 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

Carbon 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 ...

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

Carbon 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‐

Electrochemical Design of Atomically Conformal Ga2O3 Buffer Layers via Cu2O‐Catalyzed Nitrate Reduction Reaction for Efficient Cu2O Photocathodes

Carbon Energy, EarlyView.
Cu2O catalyzes nitrate reduction to locally generate OH− at the electrode surface, enabling the first uniform electrochemical deposition of Ga2O3. The Cu2O/Ga2O3‐based photocathodes achieve onset potentials above 1 VRHE, 3.8% solar‐to‐hydrogen efficiency, and stable operation for over 60 h in all‐inorganic tandem PEC devices.
