The Synthesis Effects on the Performance of P2‐Na0.6Li0.27Mn0.73O2 Cathode Material for Sodium‐Ion Batteries

Battery Energy, Volume 4, Issue 2, March 2025.
The effect of reagents on the structure and performance of sodium‐layered oxides has not yet been thoroughly studied. This work explored this factor systematically through in situ high‐temperature XRD. The samples synthesized via MnCO3‐based precursors form the Li2MnO3 phase at evaluated temperature and perform better than those through MnO2‐based ...

Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

EcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...
