Kinetics of photocatalytic decomposition of Fenuron over TiO2 in aqueous solution
The kinetics of the photocatalytic degradation of Fenuron (3-phenyl-1,1-dimethylurea) in aqueous suspension of several semiconductors irradiated at 365nm has been investigated. The kinetics of the reaction is well described by the Langmuir-Hinshelwood model showing that the degradation reactions occ...

| description | The kinetics of the photocatalytic degradation of Fenuron (3-phenyl-1,1-dimethylurea) in aqueous
suspension of several semiconductors irradiated at 365nm has been investigated. The kinetics of the
reaction is well described by the Langmuir-Hinshelwood model showing that the degradation reactions occur
on the semiconductors particles surface. The primary photoproducts were identified by RMN and GC/MS.
The main initial reaction is hydroxylation in ortho and para position with respect to the urea function. The
rate of the photocatalytic degradation increases upon addition of small amounts of hydrogen peroxide, but
is slightly reduced by chloride ions. |
