Efficient Photocatalytic Removal of Toluene by Synergistic FeCe/TiO2: Performance and Mechanism
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Efficient removal of volatile organic compounds (VOCs) in confined spaces is crucial for environments such as spacecraft and deep‐sea submarines. Metal modification is an effective strategy to enhance the light absorption capacity of titanium dioxide (TiO2) and suppress the recombination of photogenerated charge carriers.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Lithium–sulfur (Li–S) batteries are promising for next‐generation high‐energy‐storage systems but are hindered by polysulfide shuttle, sluggish kinetics, and volume expansion. Conventional carbon hosts struggle to simultaneously anchor and convert polysulfides efficiently.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Rationally designing an electrocatalyst to achieve stable and efficient urea oxidation reaction (UOR) is crucial but still challenging, especially for ampere‐level application. Herein, Mn and Fe dual‐doped Ni0.85Se (Mn/Fe–Ni0.85Se) catalyst is synthesized via a facile and scalable electrodeposition and followed by selenization.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The electrocatalytic co‐reduction of CO2 and nitrate (NO3− ${\text{NO}}_{3}^{-}$) to synthesize urea presents a sustainable alternative to traditional industrial processes, yet its efficiency is fundamentally limited by the kinetically mismatched activation and coupling of CO2 and NO3− ${\text{NO}}_{3}^{-}$.
