Magnetic Electrocatalysts Enabling a High‐Rate Capability in Lithium‐Oxygen Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study introduces zinc ferrite (ZnFe2O4) nanoparticles with tunable magnetic properties as bifunctional electrocatalysts for lithium‐oxygen batteries. Under an applied magnetic field, these catalysts significantly enhance oxygen reduction and evolution reactions by promoting spin‐aligned charge transfer and ion diffusion. The approach achieves high

Enhanced CO2 reduction to multi‐carbon products on CuLa bimetallic catalyst

InfoMat, EarlyView.
Electrochemical CO2 reduction offers a promising approach for carbon utilization while is limited by selectivity toward multi‐carbon products. In this work, we developed CuLa catalysts, which significantly improved C2+ selectivity towards around 75% under 200 mA cm−2.
