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

open access: yesENERGY &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

Enhancing the Ferroelectricity of MAPbI3 via Hydroxyl Groups to Boost Photocatalytic Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydroxyl groups in (EOA)2PbBr4 enable a rearrangement of the polar MA+ ions in MAPbI3, which enhances the Ps‐electric field and promotes the separation of photogenerated carriers. Consequently, the (EOA)2PbBr4/MAPbI3 composite exhibits the enhanced CO production yield in photocatalytic CO2 reduction reactions.

Doped Ta3N5 Semi‐Transparent Photoanode Enabling Stable Solar Redox Flow Cell Operation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Synergistic Al:TiO2 underlayer and La doping stabilize semitransparent Ta3N5 photoelectrodes for over 90 h of continuous operation in alkaline solution. The solar redox flow cell demonstrated 12 photocharge–discharge cycles at ∼55% coulombic efficiency using a K4Fe(CN)6|1,5‐DHAQ chemistry. Solar redox flow cells (SRFCs) are photoelectrochemical devices

CO2 Conversion Into Energy Rich Fuels Over Nascent COF Decorated‐Lead Free Halide Perovskites Hybrid Nano Catalysts: Experimental and Computational Investigation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A panoramic scheme signifies the CO2 conversion into energy‐rich fuels over nascent COF‐decorated lead‐free halide perovskite hybrid nano‐catalysts. Even though lead‐containing halide perovskites have been deemed emerging materials. However, the presence of toxic and carcinogenic lead (Pb) metal, small surface area, low charge separation, and a high ...
