Carbon‐Doped Amorphous Gallium Oxide Forms a Heterojunction With Water to Improve the Electrocatalytic Oxygen Evolution Reaction

Carbon Energy, EarlyView.
A dynamic catalyst–H2O heterojunction (CWH) forms on ACG during OER, with periodic bubble evolution modulating band bending and interfacial charge transfer. Electron–radical coupling drives the generation of •OH/•O2− species, converting Ga2O3 into GaOOH, whereas surface CO32− from C doping stabilizes the interface, suppressing catalyst dissolution and ...

Insights Into the Effect of Humic Acids Extraction From Coal on Hard Carbon Microstructure and Sodium Storage Properties

Carbon Energy, EarlyView.
This study employs a simple solid‐phase alkali‐oxygen oxidation (SAO) method to extract inherent components (humic acids) from coal. We successfully extracted yellow, brown, and black humic acids by adjusting the amount of alkali. Among them, brown humic acid extraction created abundant ultra‐micropores and closed pores, greatly enhancing sodium ...

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.

Ultrafast Synthesis of a Non‐Noble FeCoNiCrZn Multi‐Element Alloy Electrocatalyst for Alkaline Oxygen Evolution Reaction

Carbon Energy, EarlyView.
A nanoporous carbon‐coated FeCoNiCrZn multi‐element alloy on carbon cloth (FeCoNiCrZn‐C@CC) is fabricated by ultrafast pulsed laser irradiation. It has excellent OER performance, achieving an overpotential of only 233 mV at 10 mA cm−2 and remarkable stability for 94 h at 250 mA cm−2, which is due to multiple factors.
