Efficient Photocatalytic Removal of Toluene by Synergistic FeCe/TiO2: Performance and Mechanism
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Efficient removal of volatile organic compounds (VOCs) in confined spaces is crucial for environments such as spacecraft and deep‐sea submarines. Metal modification is an effective strategy to enhance the light absorption capacity of titanium dioxide (TiO2) and suppress the recombination of photogenerated charge carriers.

Visible‐Light‐Excited Optical Thermometry in Ca3Sc2Si3O12: Er3+ via an Efficient Eu2+ Bridge
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Er3+ ions are promising for optical thermometry due to their thermally coupled levels. However, their parity‐forbidden transitions result in weak and narrowband absorption, which restricts excitation to infrared lasers (e.g., 808, 980, or 1550 nm). Moreover, the single emission center inherently limits temperature sensitivity. In this work, we

, 2003 TiO2光催化剂薄膜在自洁、防雾功能方面具有广阔的应用前景，但其实际应用场合大多在太阳光和室内弱光下，而锐钦矿型TiO2的光吸收闭值在388nm，只能利用太阳光谱中的5％左右，对室内弱光中的可见光利用率更低。因此如何使光催化剂的吸收光红移，扩展其光谱响应范围，同时提高可见光活性和催化效率是光催化研究的热点之一。研究光催化剂可见光活性的机理不仅对设计开发高效光催化剂有指导意义，而且还具有学术意义。本文运用磁控溅射技术在浸渍一提拉法制得的TiO2薄膜上溅射氧化钨层 ...

Fe3O4@Ag3PO4/AgCl光催化剂的制备及光降解性能研究
Gongye shui chuli, 2021 光催化作为一种绿色环境治理技术，成为学界的重要研究方向之一。然而，绝大部分光催化反应需要依靠紫外光激发，发展前景受到极大限制。采用两步沉淀法制备了磁性可见光催化剂Fe3O4@Ag3PO4/AgCl，通过X射线衍射（XRD）、透射电子显微镜（TEM）和紫外-可见吸收光谱（UV-Vis）对其进行结构和组成特性分析。与此同时，以亚甲基蓝（MB）为目标污染物，研究了Fe3O4@Ag3PO4/AgCl光催化剂的可见光催化降解性能。XRD和TEM分析表明，Fe3O4@Ag3PO4 ...

Gongye shui chuli, 2016 以尿素为氮源，采用溶胶凝胶法制备N掺杂TiO2，然后与钨酸铵混合研磨，通过高温焙烧的方法原位制备WO3复合N掺杂TiO2的异质节光催化材料。分别采用X射线衍射（XRD）、紫外-可见分光光度计（UV-Vis）对样品进行分析，考察样品的光吸收阈值变化。以亚甲基蓝为降解底物，考察了样品的可见光催化处理染料废水效果，结果表明，原位制备的WO3和N掺杂TiO2异质节光催化材料对亚甲基蓝表现出良好的可见光催化活性。

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT VO2 is a promising thermochromic material, but it is still limited by low transparency, weak solar modulation, and poor stability. Here, we develop a coordination‐compound‐derived strategy to construct a hierarchical BiVO4/VO2@BiVO4 film with a core–shell@nanosheet structure.
