ABSTRACT:
A method of decomposing a fluorine-containing organic material, which includes irradiating a mixture of an aqueous phase containing a photocatalyst with the fluorine-containing organic material with light in the presence of an oxygen source. The fluorine-containing organic material may be contained in a carbon dioxide phase such that the aqueous phase and the carbon dioxide phase are mixed with each other with stirring to form a mixed phase which is irradiated with the light.
