Excellent Visible-Light Photocatalysis of Fluorinated Polymeric Carbon Nitride Solids

Fluorination of polymeric carbon nitride solids has been performed by using ammonium fluoride as a cheap fluorine source. It is clear that fluorination not only provides the modified open texture but also enables the effective adjustment of the electronic band gaps, which makes them exhibit excellent photocatalytic activity in both hydrogen production from water and oxidization of benzene to phenol under visible light.
