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.

Toward decarbonization of the titanium industry via hydrogen plasma smelting reduction

Advanced Science, EarlyView.
Hydrogen plasma smelting reduction enables direct, zero‐carbon conversion of low‐grade ilmenite into steel‐grade iron and a titania‐rich precursor for pigment production. The single‐step process merges smelting and refining, sharply lowers silica content, and offers a breakthrough path for sustainable, high‐value extraction from abundant mineral sands.

Trifunctional DOPO‐Engineered Polypropylene Separator With Li⁺‐Concentrating Interfaces for High‐Safety Lithium‐Ion Batteries Under Extreme Conditions

Advanced Science, EarlyView.
A DOPO‐based cross‐linked polymer creates a multifunctional separator for lithium‐ion batteries. It concurrently addresses safety (flame retardancy, thermal stability) and performance (enhanced Li+ transport, capacity retention), pioneering a novel approach to high‐performance battery design. Abstract This study develops a cross‐linked polymer modified

Self‐Stabilized Heterometallic Pair Sites for Selective Ethanol Dehydrogenation on Pt–Cr–Ag Alloy Catalysts

Angewandte Chemie, EarlyView.
Trimetallic PtxCrxAg1‐x (x < 0.1) alloys feature active Pt–Cr pairs for non‐oxidative ethanol dehydrogenation. Operando X‐ray spectroscopy confirms the preferential formation of Pt–Cr pairs dispersed throughout an Ag matrix and demonstrates that the Pt–Cr sites have high activity and selectivity for catalytic ethanol dehydrogenation, while suppressing ...
