What is the impact of pumping air bubbles during photocatalysis application using N doped TiO2?

09 March 2016 1 7K Report

Dear All

I did not pump air bubbles to my sample during the photocatalysis. Is there a big effect on the mechanism especially in visible light

Regards,

Haibin Li

In my opinion, firstly, pumping air bubbles increases the O2 concentration in the photocatalytic suspension, which facilitates the transfer of electrons from photocatalyst to O2, forming more superoxide radicals for photocatalytic reactions. Secondly, pumping air bubbles stirs the suspension, also favoring photocatalytic reactions.
