摘要

The uniform ZnO seed film was fabricated on the inner wall and then ZnO nanorod arrays were obtained on the inner surface of the capillaries. Methylene blue (MB) was used as a model compound on evaluate the photocatalytic activity of the microreactors. The effect of residence tithe to the photocatalytic activity and the long-term performance of the microreactors were investigated. The results show that at the residence time of 80 s, the, photodegradation rate of MB is 95% and when it is repeatedly used for 180 h, the photocatalytic efficiency is still more than 80%.
