Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Multicomponent transition metal oxides (TMOs) incorporating rare‐earth (RE) elements have emerged as promising materials for the oxygen evolution reaction (OER). However, knowledge of how to regulate the structure of TMO‐based nanomaterials through RE incorporation to enhance catalytic performance remains limited.

Gongye shui chuli, 2018 采用CaCl2对浒苔进行处理，研制出浒苔基吸附剂。通过静态吸附实验考察了该吸附剂对结晶紫的吸附性能。并进行了表面形貌和官能团分析。研究结果表明，吸附剂投加量、pH、吸附时间和温度对吸附性能影响较大。吸附过程符合伪二级动力学方程和Langmuir等温吸附模式，为快速吸附和单分子层吸附，其最大吸附量为1 000 mg/g。吸附机理是染料分子与浒苔细胞壁里纤维素和果胶中的—OH、—C—O等官能团之间存在静电吸引、氢键作用以及范德华力的作用。

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.

Gongye shui chuli, 2023 以Ce（NO3）3·6H2O和Zn（NO3）2·6H2O为原料，采用共沉淀法制备Ce-Zn复合吸附剂，利用傅里叶变换红外光谱（FT-IR）、X射线衍射（XRD）、扫描电镜（SEM）对其进行表征，对吸附过程进行动力学和热力学拟合，通过正交实验确定吸附除磷的最佳工艺条件，并对吸附剂进行再生处理，研究其可循环利用性能。结果表明，复合吸附剂表面生成了水合氧化铈和氧化锌颗粒，表面粗糙，呈多孔结构；磷酸盐离子取代复合吸附剂表面的金属羟基是吸附除磷的主要原因。除磷最佳工艺条件：磷初始质量浓度为5 mg/L，pH为4 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The stability of aqueous Zn2+ batteries is severely hindered by parasitic reactions at the Zn anode/electrolyte interface. Herein, itaconic acid (IA) is introduced as an effective electrolyte additive to achieve a highly stable zinc anode. Remarkably, IA concurrently modulates both the zinc anode/electrolyte interfacial structure and the Zn2 ...
