Surface Reconstruction of Ce‐Ion‐Doped Fe‐MOF for Efficient Water Oxidation
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Surface reconstruction plays an important role in catalysts for the efficient oxygen evolution reaction (OER). In this work, we report the designed synthesis of the Ce‐ion‐doped Fe‐MOF (CFM) directly grown on nickel foam via a facile solvothermal route.

Gongye shui chuli, 2013 制备了天然斜发沸石负载TiO2光催化剂,以染料活性黑溶液为降解目标物,紫外光为光源,在超声波协同作用下光催化降解染料废水,对催化剂的合成条件、催化活性及其重复使用性进行了研究。结果表明,在200℃焙烧温度下,由钛酸四丁酯与斜发沸石复合制备的催化剂具有最大的光催化活性,且其催化活性与纯TiO2相近。制备的催化剂质量稳定,可重复使用。超声波-光催化协同作用对染料的脱色率好于单一的光催化降解作用。

Research Progress and Prospect of Single‐Atom Materials in Tumor Catalytic Therapy
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Tumor catalytic therapy (TCT), an emerging therapeutic modality, exerts specific cytotoxic effects on tumor cells by catalyzing endogenous substances within the tumor microenvironment (TME)—including hydrogen peroxide (H2O2), glucose, and glutathione—to generate reactive oxygen species (ROS) or deplete protective biomolecules.

Gongye shui chuli, 2012 制备了Ce掺杂的TiO2复合SiO2光催化剂(Ce-TiO2/SiO2)，使用该光催化剂在模拟太阳光下催化降解亚甲基蓝水溶液，研究了催化剂用量、亚甲基蓝初始质量浓度、溶液pH、无机阴离子对光催化降解效果的影响．结果表明:n(Ce)∶n(Ti)∶n(Si)=0.002∶1∶1时所制催化剂的光催化活性最好;对于2.5 mg/L、pH为11的亚甲基蓝溶液，投加100 mg/L的光催化剂反应2 h可达到最高降解率(92.6%);NO3-、SO42-、Cl-的存在对光催化降解具有抑制作用．

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Currently, the photocatalytic performance of ZnO has been severely limited by its weak light response ability and sluggish charge carrier dynamics, which considerably hinder its extensive application in photocatalytic fields. Herein, through anchoring the synthesized K6PMo11FeO40·nH2O (PMo11Fe) onto ZnO nanosheets, a novel S‐scheme ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Platinum‐based electrocatalysts are fundamentally constrained by strong oxygen binding, which restricts the oxygen reduction reaction (ORR) kinetics, and by severe CO poisoning, which hinders the methanol oxidation reaction (MOR). To address these limitations, we synthesized PdPtRuIrRhNi high‐entropy alloy (HEA) mesoporous nanotubes that ...

Advances in Thermoelectric Cu2ZnSnS4: From Structure, Synthesis to Performance
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Thermoelectric technology has the capacity to directly convert waste heat into electricity and vice versa. For a long time, Cu2ZnSnS4 (CZTS) has been extensively researched in the domains of solar cells and photocatalysis due to its exceptional photovoltaic properties, but its wide bandgap prevents it from being favored in thermoelectrics ...
