Abstract Understanding of fundamental mechanism and kinetics the oxygen evolution reaction (OER) is pivotal for designing efficient OER electrocatalysts owing to its key role in electrochemical energy conversion devices. In past few years, lattice oxidation (LOM) arising from anodic redox chemistry has attracted significant attention as it involves a direct O─O coupling thus bypasses thermodynamic limitations traditional adsorbate (AEM). Transition metal‐based oxyhydroxides are generally acknowledged real catalytic phase alkaline media. particular, their low‐dimensional layered structures offer sufficient structural flexibility trigger LOM. Herein, comprehensive overview provided recent advances anion LOM‐based electrocatalysts. Based on analyses electronic structure LOM, strategy proposed activate Possible identification techniques corroboration also reviewed. addition, reconstruction process induced by LOM focused importance multiple situ/operando characterizations highlighted unveil chemical origins To conclude, prospect remaining challenges future opportunities presented.

Visible-light-driven CO2 photoreduction over atomically strained indium sites in ambient air

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Март 1, 2025

Strain engineering offers an attractive strategy for improving intrinsic catalytic performance of a heterogeneous catalyst. Herein, we successfully create strain into layered indium sulfide (In2S3) at atomic scale via introducing oxygen coordination and sulfur vacancy using wet-chemistry method. The atomically strained In2S3 exhibits greatly enhanced CO2 photoreduction performance, achieving to CO conversion rate 5.16 μmol gcatalyst−1 h−1 under visible light illumination in ambient air. In-situ spectroscopic measurements together with theoretical calculations indicate that the features lattice disordered defects on surface, which provides rich uncoordinated sites induces structural distortion, resulting modified band structure promotes adsorption/activation boosts photogenerated charge carriers' separation during photoreduction. This work new approach rational design photocatalysts reduction Achieving visible-light-driven air is significant yet challenging. Here, authors introduce promoted activation boosted carrier atmospheric
