Redox‐Dependent Luminescence in a Pentavalent Uranyl Complex

ChemistryEurope, EarlyView.
Redox‐dependent luminescence in a molecular pentavalent uranyl complex supported by a pyridine dipyrrolide pincer ligand is presented. Electrochemical and chemical reduction of the uranyl(VI) species provides a stable uranyl(V) complex that emits blue light from a high‐energy excited state. The anti‐Kasha emission is credited to the presence of “nested”

The Newly Discovered Pathway for Oxygen Evolution Reaction: In‐Situ/Operando Characterization Techniques for Catalyst Development

Carbon Energy, EarlyView.
This study introduces a newly discovered oxide path mechanism (OPM) for the oxygen evolution reaction (OER), emphasizing the role of in‐situ and operando characterization techniques in unraveling catalyst behavior under realistic conditions. The integration of advanced spectroscopic methods provides new mechanistic insights for the design of highly ...

Electronic Modulation of Pt Nanoparticles Induced by Defective TiN Promotes Highly Efficient Hydrogen Evolution

Carbon Energy, EarlyView.
A nonequilibrium high‐temperature shock method was used to load Pt nanoparticles onto nitrogen vacancy‐rich TiN, enabling strong EMSI modulation. The Pt@TiN‐VN catalyst shows high HER activity (15.99 A mgPₜ⁻¹ at 100 mV) and 60‐h stability. Nitrogen vacancies optimize charge transfer and Pt–H bonding, offering insights into defect‐engineered ...

Fe‐Facilitated Deep Reconstruction of Ni3S2 Toward Superior Oxygen Evolution

Carbon Energy, EarlyView.
In situ Raman spectroscopy combined with density functional theory (DFT) reveals that Fe substitution is able to facilitate the deep reconstruction of Ni3S2 into oxyhydroxides (DR‐(Ni,Fe)OOH), inducing a downshift in the energy band structure, optimizing oxygen‐containing intermediates adsorption, and thereby improving the performance of the oxygen ...

Regulating Defect‐Coordinated Single‐Iron‐Atom Catalysts for Efficient Nitrate Reduction Reactions

Carbon Energy, EarlyView.
This figure illustrates the ball‐and‐stick model of an asymmetric monatomic Fe─N2 catalyst and its catalytic process for converting nitrate to ammonia. Shown are the adsorption configurations of precursors and intermediates (NO3− → NO2− → NO → NH2OH → NH3) on the catalyst surface, where brown represents iron atoms, red represents oxygen atoms, dark ...
