摘要

基于二氧化钛的一维纳米结构由于其物理和化学性质而成为理想的产品。本文介绍了以钛白绿矿为原料生产二氧化钛纳米管及其加工产品。以Pizhemskoe矿床钛辉重精矿为原料，在碱性溶液中采用水热法合成了二氧化钛纳米管。在样品中，我们发现石英和钛酸钠的相为NaxH2-xTi3O7。纳米结构增加了比表面积，减小了带隙。我们评估了合成样品在光催化分解水中有机污染物中的有效性。我们表明，它们的有效性并不逊于商业类似物。

Natural titanium dioxide nanotubes

One-dimensional nanosized structures based on titanium dioxide are a desirable product because of their physical and chemical properties. The article considers production of titanium dioxide nanotubes based on ilmenite-leucoxene ores and products of their processing. Titanium dioxide nanotubes were synthesized by hydrothermal treatment in an alkaline solution from a gravity concentrate of ilmenite-leucoxene ore from the Pizhemskoe deposit. In the samples we found phases of quartz and sodium titanate NaxH2–xTi3O7. Nanostructuring results in increasing specific surface area and decreasing band gap. We evaluated effectiveness of synthesized samples in the photocatalytic decomposition of organic pollutants in aqueous solutions. We showed that they were not inferior to commercial analogues by their effectiveness.
