Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The precise quantification of cytokines is crucial for monitoring disease onset and progression. Herein, we developed a synergistic signal amplification approach by utilizing nanoreactor‐encapsulated CeO2 nanozymes, which were in situ electrodeposited within the mesoporous silica nanochannel film (SNF) grown on indium tin oxide (ITO ...

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 ...

, 2012 以非贵金属铁盐为催化剂,考察不同浓度的Fe_2(SO_4)_3溶液、初始反应温度和不同进液速率下的固态NaBH4水解产氢性能。实验表明:相同浓度下,Fe_2(SO_4)_3的催化产氢性能高于Fe(NO_3)_2和FeC1_3。在Fe_2(SO_4)_3溶液浓度为1.5mol/L时产氢速率出现最大值,提高Fe_2(SO_4)_3浓度,可提高平均产氢速率;在20~48℃范围内,随反应温度的升高,产氢转化率略有上升,最终均能达到90 ...

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 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.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The protracted incubation time has long been the Achilles' heel of the promising 2LiBH4–MgH2 hydrogen storage system. Instead of the usual route‐creating heterogeneous nucleation sites to hasten MgB2 formation, we shortened both de‐ and re‐hydrogenation incubation periods by steering the Mg transformation itself.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Photocatalytic hydrogen evolution technology is a crucial approach to achieve efficient solar energy conversion and green hydrogen production. However, traditional semiconductor photocatalysts often face issues such as weak visible‐light response, high photogenerated charge carrier recombination, and poor structural stability, severely ...
