Recent Advances in Tailoring Active Site Microenvironments of Fe–N–C Catalysts for Oxygen Reduction

ChemistryEurope, Volume 4, Issue 2, February 2026.
This review summarizes the main factors affecting Fe–N–C catalysts for ORR: activity depends on active site structure, electronic configuration, and porosity, while stability is limited by metal leaching, carbon degradation, and inactive phase formation.

High Potential Isoindoline‐Based Nitroxides Posolytes for Aqueous Organic Redox Flow Batteries

ChemSusChem, Volume 19, Issue 3, February 2026.
A convenient metal‐catalyzed [2 + 2 + 2] cycloaddition enables the synthesis of isoindoline‐based nitroxides as new posolytes for aqueous organic redox flow batteries. The cationic PPO exhibits a 220 mV higher oxidation potential than 4‐TMA‐TEMPO, 3 M solubility in 1 M NaCl, and a cell voltage of 1.56 V.

Electronic Modulation of Cu Sites via Iron Incorporation in Cu5FeS4 Bimetallic Sulfide for High‐Efficiency Oxygen Reduction Reaction

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The sluggish kinetics of the oxygen reduction reaction (ORR) necessitate developing oxygen electrodes with enhanced electrocatalytic activity for practical zinc–air battery applications. In this study, an iron‐doped copper sulfide electrocatalyst (CuFeNS‐PNC) anchored on metal–organic framework‐derived carbon substrates was designed, featuring
