本研究是致力于通过调整纳米二氧化钛的结构来提高光催化性能的持续研究工作的一部分。本研究涉及悬浮等离子喷涂制备具有多孔微结构和高光催化活性的黑色二氧化钛涂层。黑色二氧化钛具有锐钛矿型、金红石型、介稳板钛矿型和Ti2O3型复合结构,禁带宽度明显变窄,为2.71 eV。进一步的透射电子显微镜表征表明,黑色二氧化钛的形成与颗粒生长和巨大的晶格无序有关,这些无序是可见光吸收的主要原因。黑色二氧化钛涂层的光催化性能测试表明,在可见光下对亚甲基蓝的吸收和降解增强,这对构建用于光催化应用的黑色二氧化钛表面涂层具有启发意义。
The present study is a part of continuing research efforts devoted to modifying nano titania by tailoring its structure for enhanced photocatalytic performances. The study concerns suspension plasma spray fabrication of black titanium dioxide coatings with porous microstructures and high photocatalytic activity. The black titania showed composite structure comprising anatase, rutile, metastable brookite, and Ti2O3with markedly narrowed band gap of 2.71 eV. Further TEM characterization revealed that formation of the black titania was associated with grain growth and with tremendous lattice disorders, which are predominately responsible for visible light absorption. Examination of photocatalytic performances of the black titania coatings showed enhanced absorption and degradation of methylene blue under visible light, giving inspiring insights into surface coating construction of black titania for photocatalytic applications.
