Light induced elimination of mono- and polychlorinated phenols from aqueous solutions by PW(12)O(40)(3-). The case of 2,4,6-trichlorophenol

Article Abstract:

Researchers from Italy and Greece discovered that chlorinated phenols in aqueous solutions undergo photocatalytic (near visible-UV light) mineralization in the presence of polyoxometalates.

Formation of condensation products in advanced oxidation technologies: the photocatalytic degradation of dichlorophenols on TiO2

Article Abstract:

Condensation products were generated by the photocatalytic degradation of dichlorophenol (DCP) isomers on titanium dioxide. The six isomers have undergone total mineralization through photocatalysis. Irradiated DCPs generated condensation products in greater numbers when run for short time periods. The treatment also generated intermediates with product retention times between 15 and 22 min.

Photocatalytically assisted hydrolysis of chlorinated methanes under anaerobic conditions

Article Abstract:

Chlorinated methanes appear to degrade through photocatalytically enhanced hydrolysis methods. Combined reductive and oxidative dehalogenation of chloromethanes occured at pH5 and pH 11 under anaerobic conditions. Photocatalytically assisted hydrolysis proves faster and more useful than the other thermal process. Results indicate that halomethanes are better hydrolysed in the absence of oxygen under photocatalytic conditions.
