Light‐Promoted Hydrazine Dehydrogenation over Ni/NH2‐MIL‐125: Unraveling Mechanisms for Efficient Hydrogen Production

Advanced Science, EarlyView.
Highly dispersed and electron‐rich Ni nanoparticles (≈2.7 nm) supported on NH2‐MIL‐125 significantly promote the dehydrogenation of hydrous hydrazine under visible‐light irradiation, achieving a turnover frequency of 220.2 h−1 at 323 K, which is more than twice that in the dark (108.1 h−1) and outperforms most reported non‐precious metal catalysts ...

Ultrafine Ru‐M Alloy@S Vacancy‐Rich MoS2 Nanosheets With Bimetallic Active Sites for Efficient Hydrogen Evolution in Alkaline and Acidic Media

Advanced Science, EarlyView.
A USMR synthesizes ultrafine RuCo alloy on S‐vacancy‐rich 1T phase MoS2. This method enables rapid precursor mixing, instantaneous reduction, and uniform alloy dispersion while creating S vacancies. The synergy between Ru‐Co sites and defective MoS2 optimizes hydrogen kinetics, achieving a low overpotential of 31 mV@10 mA·cm‐2 in acid, providing a ...

Support‐Intensified Ir─P/O─Mo Cooperative Linkages for Robust Acidic Water Dissociation

Advanced Science, EarlyView.
An electrocatalyst with the coexisting Ir‐O‐Mo and Ir‐P‐Mo linkages is rationally synthesized for achieving exceptional bifunctional performance in acid solution. Abstract The efficient production of hydrogen via acidic water electrolysis is hampered by the sluggish kinetics of the oxygen evolution reaction (OER) and the scarcity of robust bifunctional

Molecular Weaving of Mixed‐Addenda Polyoxometalates into MOF Nanochannels as Electron‐Buffering Reservoirs for Enhanced Nitrate‐to‐Ammonia Electrocatalysis

Advanced Science, EarlyView.
Synergistic interaction between P2W17V1 and FeMOF owing to its efficient proton/electron transfer affording high yield and Faradaic efficiency in electrocatalytic nitrate reduction to ammonia. ABSTRACT Electrochemical conversion of nitrate pollutants into value‐added ammonia (e‐NO3RA) offers a sustainable pathway for nitrogen valorization, yet hinges ...
