The selective photocatalytic oxidation with O as oxidant of valencene and thymol was evaluated using nanostructured TiO under UV-Vis radiation at atmospheric conditions. The effect of the morphology and optical properties of TiO nanotubes and aminate nanoparticles was studied. Different scavengers were used to detect the presence of positive holes (h), electrons (e), hydroxyl radicals (•OH), and the superoxide radical anion (O) during the photooxidation reaction. Superoxide anion radical is the main oxidizing specie formed, which is responsible for the selective formation of nootkatone and thymoquinone using aminated TiO nanoparticles under 400 nm radiation.
采用纳米结构 TiO 在大气条件下的紫外可见辐射下，以 O 作为氧化剂，对葑烯和百里酚进行选择性光催化氧化。研究了 TiO 纳米管和氨基纳米粒子的形态和光学性质的影响。在光氧化反应过程中，使用不同的清除剂来检测正孔（h）、电子（e）、羟基自由基（•OH）和超氧自由基阴离子（O）的存在。超氧自由基阴离子是形成的主要氧化物质，它负责在 400nm 辐射下使用氨基化 TiO 纳米粒子选择性地形成诺卡酮和百里醌。
