Synergistic Modulation of Magnetic and Dielectric Properties via La‐V Co‐Substitution in Barium Hexaferrite for Advanced Millimeter‐Wave Absorption

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The growing deployment of high‐frequency electronic systems has intensified the demand for high‐performance microwave absorption materials. In this work, we developed La‐V co‐substituted barium hexaferrites, Ba1‐xLaxFe11.9V0.1O19 (BLFVO), via a sol‐gel route.

Dual‐Metal Co‐Doping Strategy Enhances the Hydrogen Dissociation and Hydrogen Release Performance of LiBH4 Assisted by Ensemble Learning

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT LiBH4 has drawn significant attention due to its high theoretical hydrogen storage capacity of 18.5 wt%, yet its practical application is hindered by the harsh dehydrogenation conditions. This paper proposes a strategy integrating ensemble learning with density functional theory (EL–DFT) for rapidly screening modified LiBH4 systems that ...

Tuning Y‐Mg Supports for Improved Ni‐Catalyzed NH3 Decomposition: Structural Modulation and Mechanistic Insights

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Catalytic NH3 decomposition has garnered substantial attention for hydrogen transformation and storage. Ni‐based catalysts continue to suffer from limited thermal stability and suboptimal low‐temperature activity, largely attributed to an incomplete understanding of the structure‐activity relationships and reaction mechanisms governing their ...

Atomically Dispersed Platinum Sites Immobilized on NiFe LDH by Controlling Localized Amorphization for Efficient Alkaline Electrocatalytic Hydrogen Evolution

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Platinum (Pt) single‐atom catalyst (SAC) shows great promise for hydrogen evolution reaction (HER), but faces a huge challenge in activity enhancement due to the isolated single‐atom sites. Fabricating support with partially amorphous (pa) structures to realize the synergetic interaction in neighboring single atoms could facilitate H2O ...

Upcycling of Waste Polyethylene Terephthalate Plastics to Fabricate Cobalt–Nickel Metal–Organic Frameworks and Their Phosphides for Efficient Oxygen Evolution Reaction

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves
