Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Improving the efficiency and stability of oxygen evolution electrocatalysts remains essential for advancing water splitting technologies. Although in situ surface reconstruction into active phases is desirable, it often leads to uncontrolled structural degradation.

Inverse Thermal Softening Behavior in a High‐Entropy Alloy Under Various Strain Rates
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Although face‐centered cubic high‐entropy alloys (HEAs) have received extensive attention and in‐depth research, most existing studies focus on single temperature or strain rate conditions, lacking systematic investigations into deformation mechanisms under extreme thermomechanical coupling environments.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Photocatalytic hydrogen peroxide (H2O2) production from water and oxygen driven by solar energy represents a highly promising green and sustainable strategy. Herein, lignin‐derived carbon quantum dots (LCDs) were strategically introduced at the heterojunction between a Bi‐based metal organic framework (Bi‐MOF) and ZnIn2S4 (ZIS).

Functionalized Silica‐Constructed Self‐Supporting Composite Separator for Lithium Metal Batteries
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Lithium metal batteries (LMBs) are considered highly promising next‐generation energy storage systems owing to their exceptionally high theoretical specific capacity and ultralow electrochemical potential. Nevertheless, the practical deployment of LMBs is still severely restricted by the uncontrollable formation and propagation of lithium ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The central challenge in photocatalysis is to direct photogenerated electrons and holes toward the simultaneous and efficient production of hydrogen and value‐added chemicals. To address the pronounced charge recombination and sluggish surface kinetics of ZnIn2S4 nanoflowers, we construct a ternary photocatalyst synergistically decorated with ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Metal–organic framework (MOF) membranes are a novel class of composite membranes. They use crystalline porous MOF materials as separation layers or functional fillers. Because of their well‐ordered and tunable pore structures and highly controllable chemical environments, MOF membranes show broad application prospects in gas separation ...
