A photocatalytic microreactor was developed and examined the processes of reduction and oxidation of organic compounds, and amine N-alkylation reaction in microspace. These model reactions proceeded very rapidly, and the yield increased as increasing the surface-to-volume ratio. In contrast to the result in a batch reactor, I successfully observed N-alkylation reaction of benzylamine by using the microreactor with immobilized Pt-free TiO_2 as well as TiO_2/Pt. The use of continuous-flow micoreactor inhibited the formation of N,N-dialkylation products. Since the electron-hole recombination within the photocatalyst is in competition with the reaction process, the reaction efficiencies must be strongly affected by the surface-to-volume ratio of a photocatalytic reactor. Thus the photoreaction can proceed so rapidly in the microreactor which has a remarkably large surface-to-volume ratio as compared with the conventional batch reactors.

研制了一种光催化微反应器，考察了微空间中有机物的还原、氧化和胺的N-烷基化反应过程。这些模型反应进行得非常迅速，并且产率随着表面积与体积比的增加而增加。与间歇式反应器中的结果相比，我成功地观察了无铂TiO_2和TiO_2/Pt微反应器中苄胺的N-烷基化反应。连续流动微反应器的使用抑制了N，N-二烷基化产物的形成。由于光催化剂内的电子-空穴复合与反应过程竞争，因此反应效率必须受到光催化反应器的表面积与体积比的强烈影响。因此，与常规间歇式反应器相比，光反应可以在具有显著大的表面积-体积比的微反应器中如此迅速地进行。
