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。

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.

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 7, July 2026.ABSTRACT Because of superior transportability and high energy capacity, methanol is regarded as a potential hydrogen carrier. Photocatalytic methanol dehydrogenation offers a sustainable and cost‐effective method for releasing hydrogen. Conventional photocatalysts face challenging obstacles, including the low catalytic efficiency and rapid ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Defect engineering has been widely demonstrated as an effective strategy for enhancing the activity of OER metal catalysts, among which the introduction of twin boundaries (TBs) has proven particularly efficient. However, single‐type defects offer limited performance enhancement.

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.
