Differently modified TiO2 nanotubes were used to achieve a drastic change in the selectivity of a photocatalytic reaction. For the photocatalytic oxidation of toluene, depending on the electronic properties of TiO2 (anatase, rutile, Ru-doped), a strong change in the main reaction product (namely benzoic acid versus benzaldehyde) can be achieved, and certain undesired reaction pathways can be completely shut down.
不同修饰的 TiO2 纳米管被用于实现光催化反应选择性的剧烈变化。对于甲苯的光催化氧化，取决于 TiO2 的电子性质（锐钛矿、金红石、Ru 掺杂），可以实现主要反应产物（即苯甲酸与苯甲醛）的强烈变化，并且可以完全阻断某些不期望的反应途径。
