High‐Coverage Nanometric MOx (M = Ir, Rh) Clusters Anchored on Spinel Co3O4 Matrix With Amorphous/Crystalline Heterostructure Harness Efficient Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Strong interfacial electronic coupling between nanometric MOx (M = Ir and Rh) clusters and the spinel matrix optimizes the electronic environment and redistributes spatial charge, thereby enabling efficient water electrolysis. Architecting nanometric cluster electrocatalysts with high density of active atoms offers a valuable avenue to simultaneously ...

Sustainable Revival of Spent Lithium Iron Phosphate Cathodes in Li‐Ion Batteries: Recycling and Surface Engineering Approaches

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration of the lifecycle of LiFePO4 cathodes. Lithiation and delithiation reactions happen through its discharging and charging processes. Recycling pathways including hydrometallurgy, pyrometallurgy, and direct regeneration enable sustainable reuse of spent LFP materials. Surface modification approaches (carbon, polymer, and metal/metal

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural
