Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.

Interfacial Electronic Modulation of Vacancy‐Stabilized Pt Sites in Mo‐NiSeO4/NiSe2 Heterostructures for Industrial Alkaline Water Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
A vacancy‐stabilized Pt,Mo‐NiSeO4/NiSe2@Co2P heterostructure with atomically dispersed Pt sites and Mo‐regulated electronic structure enables efficient bifunctional water splitting. Strong interfacial coupling and defect‐assisted Pt stabilization promote rapid charge transfer and optimized intermediate adsorption, delivering outstanding HER/OER ...

Some higher-order processes in the optical absorption and emission by impurities in nonmetals

open access: yes, 1977
The effects arising from quadratic electron-phonon interaction and anharmonicity on the optical spectra of imperfections in nonmetals are examined. The absorption or emission line-shape function is expressed in terms of Kubo's formula and is reduced to a

Trash to Treasure: PFAS‐Functionalized MOFs for Boosted Piezocatalytic H2 Production

open access: yesAdvanced Energy Materials, EarlyView.
A novel pollutant‐as‐functional‐additive strategy is developed via postsynthetic modification of MOF‐808(Hf) with perfluorohexanoic acid (PFHxA), a typical PFAS pollutant. The modification boosts the dipole moment of the MOFs, enhances their piezoelectricity to promote efficient electron‐hole separation, thus delivering ultrahigh piezocatalytic ...
