Mesoporous Hexametallic High‐Entropy Alloy Nanotubes With Multicomponent Electronic Modulation for Efficient Bifunctional Catalysis

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Platinum‐based electrocatalysts are fundamentally constrained by strong oxygen binding, which restricts the oxygen reduction reaction (ORR) kinetics, and by severe CO poisoning, which hinders the methanol oxidation reaction (MOR). To address these limitations, we synthesized PdPtRuIrRhNi high‐entropy alloy (HEA) mesoporous nanotubes that ...

Revealing the Roles of Electrolyte Concentration on Transition Metal Dissolution and Reaction Pathway of Anion Adsorption Pseudocapacitance

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

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

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.

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

Rare 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 ...

Lattice Pre‐Expansion Facilitates Stable Sodium‐Ion Storage in Sn‐Based Anodes by High‐Throughput Fabrication

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The low energy density of sodium‐ion batteries (SIBs) remains a major barrier to their large‐scale deployment. Alloy‐based anodes represent a promising class of materials owing to their high specific capacity and low operating potential for sodium storage. However, their practical application is hindered by severe volume expansion upon cycling.
