Vacancy Engineered Zero‐Valent Iron Steer Hydrogen Spillover toward Per‐ and Polychlorinated Organics Rapid Complete Dechlorination

Advanced Science, EarlyView.
Zero‐valent iron with a vacancy‐rich carbon shell and lattice Cu doping in Fe0 cores generates a dechlorination mechanism combining enhanced electron transfer and modulated H* spillover, which significantly lowers the energy barrier for dechlorinating low‐chlorinated intermediates, accelerates C─Cl bond dissociation, and then delivers breakthrough ...

Optimizing Surface *H Coverage over Cu2O/Co3O4 Heterojunction Enables Efficient Neutral Electrocatalytic Hydrogenation of 5‐hydroxymethylfurfural to 2,5‐dihydroxymethylfuran

Advanced Science, EarlyView.
This work presents a heterojunction strategy, wherein Co3O4 functions as a redox‐active cocatalyst to stabilize Cu⁺ sites and finely tune the electronic structure of Cu2O. Such interfacial modulation accelerates H2O dissociation kinetics under neutral conditions and enables optimal surface *H coverage, thereby facilitating efficient HMF electro ...

Iron Nanoparticles on Porous Carbon Discs: Electrocatalysts with Over 30% Energy Efficiencies for the Production of Ammonia from Nitrate

Advanced Science, EarlyView.
Iron nanoparticles on carbon disc matrixes (CD@Fe) are engineered, showing a high surface area of 424 m2 g−1 and micro/mesoporosity. The CD@Fe showed promising electrocatalytic performance for the nitrate reduction to ammonia with ammonia yield rates of 1.8–13.5 mg h−1 cm−2 at overpotentials of −0.2–−0.6 V (vs.

Fabrication of Planar Highly Enriched Silicon by 28Si Focused Ion Beam and Subsequent Experimental Optimization

Advanced Electronic Materials, EarlyView.
The optimization of silicon enrichment via 28Si focused ion beam, demonstrating the variations in enrichment level with respect to ion beam energy, ionization state, and ion beam density. This has led to adjustments in Monte Carlo simulations (TRYDIN) to account for the difference in observed surface accumulation and recession, with a balance being ...
