The synergistic degreasing treatment of background irradiated photocatalysis and microreactor

The microreactor principle was applied to the photocatalytic degreasing process by using the self-made simple equipment. The results show whether alone by using the background irradiated photocatalysis or just by using the microreactor to the degreasing treatment of the copper foil surface, the photocatalytic degreasing rate is very low. On the contrary, the two synergistic effects of the background irradiated photocatalysis and the microreactor are not only much larger than that of single function, but much higher than that of their cumulative effect. When the light source power is 100 W and the irradiating time is 30 min, the degreasing efficiency of two synergistic effects is >  90%.
