Multi‐Cation (High‐Entropy) Doping of Mesoporous Co3O4 Thin Films With Cr, Mn, Fe, Ni, Cu, and Ag: Assessment of the Oxygen Evolution Reaction Performance

EcoEnergy, EarlyView.
Mesoporous Co3O4 thin films doped with Cr, Mn, Fe, Ni, Cu, Ag, and a multi‐cation combination were synthesized via sol‐gel dip‐coating. Structural, optical, and electrochemical analyses reveal Fe and Cu as the most effective dopants for enhancing OER activity, whereas multi‐cation doping shows no synergistic improvement.

Confinement−Adsorption Synergy in Hybrid Carbon‐Coated Separator Enables Stable High‐Rate Quinone Cathode for Magnesium Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sulfur‐containing heterocyclic quinone cathode for rechargeable magnesium batteries is coupled with a GO/MWCNTs–COOH separator that establishes a confinement–adsorption regulation mechanism, thereby significantly accelerating Mg2+ reaction kinetics and minimizing active‐material loss.

Synergistic‐Induced Perovskite Phase Distribution and Lattice Stabilization for Efficient and Stable Sky‐Blue PeLEDs

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We have developed a multifunctional buried‐interface engineering strategy using phenethylammonium thiocyanate to regulate quasi‐2D perovskite crystallization and stabilize the lattice. The synergistic effects of SCN− and PEA+ steric confinement promote phase redistribution toward n = 2, suppressing interfacial defects and enabling the production of ...

Decorating Carbon Nitride via the Integration of Phosphorylation with Carbon Self‐doping toward Enhanced Photocatalytic Hydrogen Evolution

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The electron transfer from the grafted ATMP to the adjacent heptazine ring can induce the proton transfer of the hydroxyls on ATMP to Pt co‐catalyst nanoparticles. This coupling of proton transfer and electron transport also promotes the separation and transport of charge carriers and therefore advances the performance of photocatalytic hydrogen ...

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

ENERGY &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.

Metal‐Free Halogen‐Engineered Carbon Nanotubes for Highly Efficient Oxygen Reduction Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In work employs density functional theory screening to guide the halogen engineering of metal‐free, Cl‐mediated carbon nanotubes for a highly efficient oxygen reduction reaction (ORR). Cl‐mediation optimally tunes the electronic structure and binding energies of oxygen intermediates, delivering an ORR activity rivaling that of commercial Pt/C, high 4e−

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

Managing Crystallization in Tin‐Lead Perovskite Solar Cells via Differential Chelating Coordination

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A chelation‐mediated crystallization strategy is developed for Sn–Pb perovskites using 1,10‐phenanthroline. Stronger coordination with Sn than Pb helps reconcile their mismatched crystallization behavior, leading to improved crystalline quality, fewer defects, and reduced oxidation.
