Spectroscopic Insights Into the Role of the Coverage of *CO and *H on Bifurcation of Ethylene and Ethanol Pathways in Carbon Dioxide Electroreduction

open access: yesCarbon Energy, EarlyView.
Zhao et al. control the coverage of *CO or *H intermediates by introducing foreign metal into Cu nanoparticles. The increased *CO coverage on Ag‐doped and Zn‐doped Cu promotes the generation of multi‐carbon products while the increased *H coverage of Co‐doped and Pd‐doped Cu enhances the selectivity of oxygenates. ABSTRACT As key reaction intermediates

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 ...

Mg‐Gradient Polyacrylonitrile Nanofiber Layer Enabling Li Coble Creep and Stress Relaxation in Anode‐Free All‐Solid‐State Batteries

open access: yesCarbon Energy, EarlyView.
A Mg‐gradient polyacrylonitrile nanofiber (PAN@Mg) layer is introduced on the current collector. This 2‐μm‐thick layer regulates Li diffusion via the Coble creep mechanism, preventing direct Li–solid electrolyte contact. Its elasticity effectively mitigates stress, preserving interfacial integrity during cycling. This approach enables highly reversible
