Abstract

In this research, changes in several characteristics of partially reduced titania were studied. The reduction process used made it possible to gradually observe changes in the material depending on the amount of reducing agent used. We used NaBH to impregnate commercial TiO with isopropyl alcohol. Impregnated TiO nanoparticles were dried and thermally treated in a nitrogen flow to obtain blue titania samples. Thorough spectroscopic characterization showed that oxygen atoms from hydroxyl groups, as well as from the surface, and the lattice of TiO was consumed. This caused changes in the surface and even in the bulk of TiO when the amount of reducing agent used was increased. Structural, optical, superficial, and textural characteristics were studied using XRD, Raman, DRS UV-Vis-NIR, Mid-DRIFT, XPS, and nitrogen adsorption/desorption isotherms. A photocatalytic test of the degradation of methylene blue dye was performed. Among different effects on the mentioned characteristics, we found evidence of changes in the surface properties of the blue titania samples and their probable effect on the photocatalytic properties. The reduction process implied a preponderant decrease in the surface hydrophilicity of the reduced samples, an effect shown for the first time in this type of material.

摘要

在本研究中，对部分还原二氧化钛的几个特性变化进行了研究。所采用的还原过程使得能够根据所用还原剂的量逐渐观察材料的变化。我们使用硼氢化钠用异丙醇浸渍商用二氧化钛。将浸渍后的二氧化钛纳米颗粒干燥并在氮气流中进行热处理，以获得蓝色二氧化钛样品。全面的光谱表征表明，来自羟基以及表面和二氧化钛晶格的氧原子被消耗。当所用还原剂的量增加时，这导致了二氧化钛表面甚至整体的变化。使用X射线衍射（XRD）、拉曼光谱、漫反射紫外可见近红外光谱（DRS UV-Vis-NIR）、中红外漫反射光谱（Mid-DRIFT）、X射线光电子能谱（XPS）和氮吸附/脱附等温线对结构、光学、表面和织构特性进行了研究。进行了亚甲基蓝染料降解的光催化测试。在对上述特性的不同影响中，我们发现了蓝色二氧化钛样品表面性质变化的证据及其对光催化性能的可能影响。还原过程意味着还原样品的表面亲水性显著降低，这种效应在这类材料中首次被发现。
