Synergizing Multi‐Chemisorption Sites and Micropore Confinement in Porous Carbon for High‐Performance Zinc‐Ion Hybrid Capacitors

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Aqueous zinc‐ion hybrid capacitors (ZICs) bridge the gap between high‐energy batteries and high‐power supercapacitors, yet their performance is fundamentally bottlenecked by the micropore confinement effect in carbon cathodes, which restricts hydrated Zn2+ transport and active site utilization.

Architecting a Robust Yarn‐Like CNT Framework for Structurally Resilient ZnSe Anodes in Potassium–Ion Batteries

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The development of structurally stable anodes with high capacities and long cycle lives is essential for the development of potassium–ion batteries. Conversion‐type anodes have attracted considerable attention in potassium–ion batteries (PIBs) due to their high theoretical capacities.

From Molecular Motion to Macroscopic Function: Tailoring Tetraarylethylene Supramolecular Architectures for Aggregation‐Induced Emission and Wave Absorption

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Integrating light emission and electromagnetic wave (EMW) absorption into a single material opens up possibilities for multienvironmental applications. Herein, we propose a novel “molecular engineering‐pyrolysis conversion” strategy to construct a bifunctional system with tunable photoluminescence and efficient EMW absorption performance.

氮掺杂碳纳米管对其负载的Ru催化剂上合成氨的促进作用

, 2011
以乙腈为碳源和氮源,采用化学气相沉积法制备了氮掺杂的碳纳米管.电子显微镜观察表明,样品形貌为中空的多壁纳米管,管腔大小10～15nm,壁厚10～20nm.X射线光电子能谱结果表明,氮已掺杂到碳纳米管结构中,主要以吡啶型氮和取代型氮存在.结合X射线衍射和拉曼光谱结果发现,随着制备温度的升高,氮掺杂量减少,但纳米管的石墨化程度提高.与未掺杂碳纳米管相比,氮掺杂碳纳米管负载的Ru催化剂上催化合成氨反应活性增加,于650oC制得的掺氮碳纳米管负载的Ru催化剂活性相对最高 ...

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

Rare 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

Rare 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
