Reaction order of photocatalytic degradation of various organic compounds
Krýsa, J. ; Waldner, G. ; Jirkovský, Jaromír ; Grabner, G.
The kinetic of photocatalytic degradation of four different model organic compounds, formic acid (FA), oxalic acid (OA), 4-chlorophenol (4-CP) and 3-(4-chlorophenyl)-1,1-dimethylurea (the herbicide monuron), on irradiated titanium dioxide was compared.
Surface complexation and charge transfer processes in colloidal semiconductors studied by laser flash photolysis
Grabner, G. ; Jirkovský, Jaromír
Aqueous colloidal solutions of quantum sized particles of TiO2 undergo an ageing process beginning with their preparation. In course of time, the mean size of nanoparticles is gradually increasing and some of their physico-chemical properties are changing as well. In the present study, the decrease of the spectral blue shift of the semiconductor absorption threshold was measured to determine the corresponding changes of band gap energy of the Q-TiO2 particles.
Photodegradation of phenylurea herbicides under simulated environmental conditions
Jirkovský, Jaromír ; Lemr, K. ; Grabner, G.
Kinetics and mechanicm of the photoinduced degradation of 4-chloroaniline (4-CA), a toxic metabolite of phenylurea herbicides, have been studied in detail.
