Multifunctional Integration in a Monolithic Biomass Carbon: A Triple‐Synergistic Host for Advanced Lithium–Sulfur Batteries

open access: yesRare 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.

Dual‐Site Electronic Modulation in Mn/Fe‐Doped Ni0.85Se for High‐Efficiency Urea Oxidation at Industrial Current Density

open access: yesRare 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.

Synergetic Ruthenium Clusters and Ligand Motifs in Insoluble Polyoxometalates for Efficient Urea Electrosynthesis

open access: yesRare 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− ${\text{NO}}_{3}^{-}$.

Copper Slag‐Derived Cu3Fe17@C Alloy Enabling Efficient Peroxymonosulfate Activation for Levofloxacin Degradation via Cu‐Mediated Electron Transfer With Suppressed Metal Leaching

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Although alloy‐based materials present potential for peroxymonosulfate (PMS) activation, metal ion leaching remains severely restricted during the pollution degradation process. Herein, the porous carbon‐supported Fe–Cu alloy derived from industrial copper slag was prepared to remove the organic pollutants from wastewater while inhibiting the ...

Doping‐Engineered Modulation of Oxygen Vacancy Formation Energy in Gallium Oxide for High‐Performance Solar‐Blind UV Photodetectors

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Solar‐blind ultraviolet (UV) photodetectors (SBPDs) play a critical role in applications including UV communication and fire warning systems. Gallium oxide (Ga2O3) has emerged as a promising material due to its wide bandgap and low cost, but suffers from high dark current and slow response speed caused by oxygen vacancy (VO) defects.
