Photocatalytic reactions in microreactors

Aphotocatalytic microreactor with immobilized TiO2 layerwas developed and the processes of degradation and reduction of organic compounds, and amine N-alkylation in microspace were examined. These model reactions proceeded very rapidly with considerably large photonic efficiencies. In contrast to the result in a batch reactor,we successfully observedN-alkylation reaction of benzylamine by using the microreactor with immobilized Pt-free TiO2 as well as TiO2/Pt. These results suggest the feasibility of a catalytic microreaction system on organic photoreactions.
