High‐Entropy Metal Phosphide for Efficient Hydrogen Conversion Reactions

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this study, high‐entropy metal phosphide nanoparticles were synthesized via a cation‐binding phosphate–resin heating treatment strategy. Mn incorporation in Co0.62Fe0.20Ni0.14Cu0.23Mn0.38P effectively optimized the electronic structure, accelerated electron transfer among metal sites, lowered the free energy of hydrogen adsorption/desorption, and ...

Bottlenecks‐Breaking in Zinc‐Iodine Batteries Toward Practical Implementation: A Review and Perspective

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Aqueous zinc–iodine batteries (Zn–I2Bs) offer promise for grid storage due to safety and cost advantages yet face critical bottlenecks: severe self‐discharge (polyiodide shuttling and HER), limited energy density, sluggish kinetics, and zinc anode instability.

Mitigating Cathodic Challenges in Aqueous Zn–I2 Batteries via Dual‐Effect Function Strategy: Concurrent I3− Immobilization and Catalysis of I0/I− Redox Kinetics

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work employs a dual‐effect function strategy of Se to make an original composite material of selenium (Se) and activated carbon (AC) (designated as Se–AC), as a functional iodine‐adsorbed cathode host. Not only Se catalyzes the I0/I− conversion reaction, but also Se nanoparticles can adjust the charge distribution of AC to adsorb more I3−. Aqueous‐

Activating and Stabilizing Lattice Oxygen in Spinel NiCo2O4 through F, Mn Dual Doping for Rechargeable Zinc–Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study exploited the substitution doping of Mn and F in NiCo2O4 to activate and stabilize lattice oxygen, achieving a stable synergistic effect between AEM and LOM to enhance the intrinsic activity of the catalyst. The outstanding bifunctional properties enable its application as an anode catalyst in zinc–air batteries.
