Bi/Bi2O3 Nanoparticles In Situ Embedded in Carbon as Anode Materials for Fast and Long‐Lasting Sodium–Ion Storage

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Bismuth anode materials are considered promising anode candidates for sodium–ion batteries (SIBs) due to their high theoretical capacity and appropriate working potential. Nevertheless, the significant volume expansion that occurs during the cycling process restricts its broader application in sodium–ion storage. Herein, Bi/Bi2O3 nanoparticles

Pyrolysis‐Engineered Fe/Mn‐ZIF Catalysts: Balancing Activity, Selectivity, and Stability for the Oxygen Reduction Reaction

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the
