High‐Entropy Alloys for Photocatalysis: From Cocatalyst Engineering to Multifunctional Active Platforms

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Photocatalysis has emerged as a promising approach for solar energy conversion and environmental remediation. However, its practical implementation is still hindered by limited charge‐separation efficiency, slow surface reaction kinetics, and insufficient catalyst stability.

Nanoporous/Nanocrystalline/Amorphous Multiphase Surfaces on Amorphous Alloy Fibers for Enhanced Oxygen Evolution Reaction Performance

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The development of high‐performance and cost‐effective oxygen evolution reaction (OER) electrocatalysts is critical for the large‐scale deployment of green hydrogen technologies. Among various candidates, amorphous alloys have emerged as promising OER catalysts owing to their long‐range disordered atomic structures, high energy states, and ...

Engineering Stress‐Decoupled SnP2O7@Carbon Core Shell via Spatial Confinement for Cycling‐Stable Sodium Storage

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Tin‐based composite oxides typically undergo severe volume variations and exhibit poor intrinsic conductivities despite their high theoretical capacity as promising anode candidates for sodium‐ion batteries. This results in rapid structural degradation and capacity fading upon cycling.

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 ...

Studies of Oxygen Reduction Electrocatalysts Enhanced by Dealloying

, 2011
Dealloying refers to the partial, selective dissolution of the less noble component(s) of a binary or ternary alloy precursor, resulting in a noble-rich, porous structure that has high surface area. Such surface structure is beneficial for fuel cells (FC)
