Enhancing Oxygen Evolution Reaction Activity in NiCo2O4 Catalysts Through Morphology and Oxygen Vacancy Engineering

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Developing oxygen evolution reaction (OER) catalysts that combine high performance with cost‐effectiveness is a critical challenge for advancing the commercialization of anion exchange membrane water electrolysis (AEMWE). Practical application is often hindered by issues such as poor batch reproducibility and low‐cost efficiency.

Designing 3d Transition‐Metal Doped g‐C3N4 Monolayer for Enhanced Bifunctional Oxygen Evolution/Reduction Reactions Activity: Defect Physics and Constant‐Potential Study

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Graphitic carbon nitride (g‐C3N4) doped with 3d transition metals (3d‐TM@g‐C3N4) has gained attention as a noble metal‐free alternative for oxygen evolution and reduction reactions (OER/ORR). Yet the key mechanisms driving its performance remain debated, especially across different charge states.

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

In Situ Formation of the Li3Bi Alloy Phase Interface for Robust Garnet Solid‐State Lithium Batteries

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Garnet‐type electrolyte Li6.4La3Zr1.4Ta0.6O12 (LLZTO) is a promising component for commercializing solid‐state batteries owing to its wide electrochemical window, good stability, and high shear modulus. However, poor interface wettability and lithium dendrite growth limit the practical application of the LLZTO electrolyte.

Construction of CoP/Mn2P Heterojunctions via One‐Step Phosphorization Coupled With Hollow Hard Carbon Spheres as Supports: Enabling Ultrastable Long‐Cycle Sodium‐Ion Anodes Over a Wide Temperature Range

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Driven by global energy transition and sustainability, sodium‐ion batteries (SIBs) have emerged as key alternatives to lithium‐ion batteries for low‐to‐medium energy storage, because of abundant sodium resources and low cost. However, their commercialization is hindered by the lack of anodes with high capacity, fast kinetics, and long‐term ...
