Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Photocatalytic hydrogen peroxide (H2O2) production from water and oxygen driven by solar energy represents a highly promising green and sustainable strategy. Herein, lignin‐derived carbon quantum dots (LCDs) were strategically introduced at the heterojunction between a Bi‐based metal organic framework (Bi‐MOF) and ZnIn2S4 (ZIS).

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The central challenge in photocatalysis is to direct photogenerated electrons and holes toward the simultaneous and efficient production of hydrogen and value‐added chemicals. To address the pronounced charge recombination and sluggish surface kinetics of ZnIn2S4 nanoflowers, we construct a ternary photocatalyst synergistically decorated with ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT A central challenge in high‐performance photoelectrochemical (PEC) systems is mitigating the intrinsic limitations in photogenerated carrier separation and transport, while enabling efficient broad‐spectrum solar harvesting. Inspired by the synergistic effect between plasmonic resonance and heterojunction built‐in electric fields, a ternary ...

四川大学学报. 自然科学版, 2009 采用激光辐照的方法在硅锗薄膜样品表面生成微米级小孔,用高精度扫描电镜观察孔内结构,发现片状的纳米结构.用荧光光谱仪测其光致荧光谱,在705nm 处出现较强的光致荧光谱(PL).对片状结构在800℃下进行退火20min 后,其 PL 光谱明显蓝移至575nm.退火40min 后,在725nm 处有较宽的 PL 光谱,同时,在606nm 处有一尖锐的 PL 光谱.利用量子受限和纳晶与氧化物的界面态综合模型解释 PL 光谱的产生.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely limit performance across wide temperature ranges. Here, we demonstrate that

四川大学学报. 自然科学版, 2009 研究了曲酸对胰蛋白酶活性的影响,以及曲酸处理的胰蛋白酶的紫外光谱、荧光淬灭光谱、同步荧光光谱和三维荧光光谱.结果显示曲酸对胰蛋白酶具有激活作用;二者相互作用后,曲酸可以使胰蛋白酶的紫外吸收强度增强,但却使得蛋白内源荧光强度下降.Stern-Volmer作图显示了曲酸对胰蛋白酶的荧光淬灭为静态淬灭作用,求出二者的结合常数K为5.30×10～7L/mol,结合位点n为1.50;用同步荧光光谱和三维荧光光谱探讨了曲酸对胰蛋白酶构象的影响.

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.
