Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Efficient catalytic materials are vital for addressing the polysulfide shuttle and sluggish redox kinetics in lithium–sulfur batteries. Herein, we report a facile sugar‐blowing method to prepare porous carbon‐supported FeCoNiCuPt high‐entropy alloy (HEA) nanospheres with abundant lattice defects in a single crystalline phase.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The Janus structure of ZnIn2S4 (ZIS) endows it with an intrinsic built‐in electric field that effectively drives photogenerated charge separation. However, this very structure also renders the predominant (001) facet (In–S termination) catalytically inert due to its low electron density and high energy barrier for the hydrogen evolution ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Layered double hydroxides (LDHs) are attractive non‐noble catalysts for overall water splitting (OWS), yet their hydrogen evolution reaction (HER) activity is often limited by suboptimal *H adsorption and a paucity of accessible sites. Herein, we introduce an oxygen‐vacancy (Ov) engineering strategy to construct ultrathin Ni‐Fe LDH nanosheets ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Water electrolysis is a promising method for green hydrogen production, but slow hydrogen evolution reaction (HER) kinetics require efficient catalysts. In this study, we develop a Ni3S2/MoS2 heterostructure electrocatalyst using a work‐function‐driven electronic modulation strategy combined with a self‐sacrificial template approach.
