Photo‐electro‐catalytic oxidation reactions of 1,6‐hexanediol were carried out in a coil‐type continuous‐flow microreactor with an immobilized TiO₂ catalyst material. Bio‐based adipic acid was formed as the only intermediate product before the total mineralization process. The production was stable, enabling green, selective and continuous resource conversion, but with low, non‐optimized yields. In addition, the catalyzed chemical kinetics was modeled, based on mechanisms as well as approximated rate‐determining steps. The Butler‐Volmer relation was used for activation. The electro‐catalytic oxidative pathway was demonstrated to dominate over photo‐catalysis, also on account of the band gap characteristics of the titania nanotube electrode.

反应动力学模型的光电催化连续合成生物基己二酸

1,6-己二醇的光电催化氧化反应是在带有固定化TiO ₂催化剂材料的螺旋式连续流微反应器中进行的。生物基己二酸是整个矿化过程之前的唯一中间产物。生产稳定，可以实现绿色，选择性和连续的资源转换，但产量低且未优化。此外，基于机理以及近似的速率确定步骤，对催化的化学动力学进行了建模。Butler-Volmer关系用于激活。事实证明，由于二氧化钛纳米管电极的带隙特性，电催化氧化途径在光催化方面占主导地位。
