Photocatalysts based on the anodic single-walled titania nanotubes modified with metal nanoparticles (Au, Pd, Pt) were prepared and investigated. The metal nanoparticles sizes are in a range from 3 to 15 nm. The wall thickness of the nanotubes varied from 14 to 17 nm. It is established that photocatalysts with Au, Pd, Pt produce acetaldehyde during complete ethanol decomposition reaction. Additionally the formation of methane occurs in the TiO nanotubes with Pd and Au nanoparticles. We obtained firstly the multifunctional TiO nanotubes modified with Pd and Au nanoparticles for use both in air purification and in the production of hydrocarbon fuel precursors.

金属纳米粒子修饰多功能TiO2光催化剂的合成与研究

制备并研究了基于金属纳米颗粒（Au、Pd、Pt）修饰的阳极单壁二氧化钛纳米管的光催化剂。金属纳米粒子的尺寸在3至15纳米范围内。纳米管的壁厚从 14 纳米到 17 纳米不等。已确定含有 Au、Pd、Pt 的光催化剂在乙醇完全分解反应过程中会产生乙醛。此外，含有 Pd 和 Au 纳米颗粒的 TiO 纳米管中也会形成甲烷。我们首先获得了用 Pd 和 Au 纳米颗粒改性的多功能 TiO 纳米管，用于空气净化和碳氢化合物燃料前体的生产。
