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.

Oxygenophilic Cerium Promotes Active Species Generation and Modulates the Interfacial Water Network in Electrocatalytic Water Oxidation

Carbon Energy, EarlyView.
CeO2 dendrites are introduced to modify the NiSx/C3N4 nanorods, constructing hexagonal star‐like forest arrays (CeO2@NiSx/C3N4). The oxophilicity of Ce species generates abundant oxygen vacancies, which subsequently facilitate the in situ evolution of active amorphous NiOOH.

Fe Atoms Accelerator Coupled With Oxygen Vacancies Channel Synergistically Boost OER Performance of Fe‐CoMoO4‐Ov Nanosheets

Carbon Energy, EarlyView.
Fe‐CoMoO4‐Ov/NF demonstrates significantly improved OER catalytic performance compared to CoMoO4. Specifically, the introduced Fe atoms act as a promoter for surface reconstruction, significantly reducing the energy required for surface reconstruction to generate FeCoOOH. The oxygen vacancies serve as electron channels between the core Fe‐CoMoO4‐Ov and
