Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Atomically dispersed iron–nitrogen–carbon (Fe‐N‐C) catalysts have emerged as promising alternatives for oxygen reduction reaction (ORR) owing to their highly atomic utilization. However, maintaining both Fe atomic dispersion and dense Fe‐Nx sites (typically below 2 wt%) in Fe‐N‐C catalysts is still a key challenge.

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.
