An Experiment of Nanometer-Sized Titanium Dioxide Photocatalyst

Photocatalysis and titanium dioxide photocatalysts is one of the important investigation subjects.In order to make undergraduates majoring in chemistry to grasp the principle of photocatalysis and preparation of photocatalyst,an experiment was designed,including the preparation of nanometer-sized anatase titanium dioxide photocatalyst by the sol-gel method and photocatalytic degradation of methyl orange.
