Test method for self cleaning performance
Peterka, F. ; Jirkovský, Jaromír ; Sťahel, P. ; Navrátil, Z. ; Buček, A.
The method for self cleaning performance is based on combination of both effects og photocatalytic function, which are ox/red reaction and surface hydrophilicity. When oleic acid, as organic material deposited on tested photocatalytic material is decomposed, surface is becoming hydrophilic.
Degradace organických polutantů ve vodném prostředí fotoindukovaná komplexem Fe(III)CIT: vliv TiO2
Kolář, Michal ; Mailhot, G. ; Jirkovský, Jaromír ; Bolte, M. ; Krýsa, J.
Tato práce se věnuje studiu komplexu trojmocného železa s citrátovými ionty a jeho účinku na fotodegradaci modelového polutantu, monuronu.
Vliv stárnutí TiO2 koloidních částic ve vodě na jejich vlastnosti
Paušová, Š. ; Jirkovský, Jaromír ; Krýsa, J. ; Mailhot, G. ; Prevot, V.
Tato práce popisuje chování vodných roztoků Q-TiO2. Hlavním cílem bylo prozkoumat stárnutí těchto koloidních roztoků při různých teplotách (4,20,40 C) a různých pH (2,5 a 11)
Competitive adsorption and photodegradation of salicylate and oxalate on goethite
Krýsa, J. ; Jirkovský, Jaromír ; Bajt, O. ; Mailhot, G.
It is known that Fe(III) aquacomplexes were proved to be efficient photocatalyst to induce the complete mineralisation of variety of pollutants. There are several crystalline polymorphs of iron oxohydroxide present in soil as well as marine sediments. Goethite was found as one of the most common components of sediments in the Gulf of Triest.
Degradation of organic pollutants in aquatic environment photoinduced by Fe(III)Cit complex: Impact of TiO2
Kolář, Michal ; Jirkovský, Jaromír ; Mailhot, G. ; Bolte, M. ; Krýsa, J.
Iron is the most abundant transition metal on the Earth. It is present in the atmosphere, soils as well as aquatic environments. In the aquatic media, it is often presnt in a form of Fe(III) complexes, especially with polycarbolic acids. The complexes of Fe(III) are highly photosensitive in general.
Photodegradation of monuron in the presence of goethite and carboxylic acids
Bajt, O. ; Krýsa, J. ; Jirkovský, Jaromír ; Zita, J. ; Paušová, Š.
Iron is one of the most abundant elements in the environment. It is also an essential micronutrient for most known aquatic organisms, Its role in primary production in natural waters is very important. However, the low solubility of iron oxides at pHs, significant the low availability of iron to aquatic plants and microorganisms. Goethite, an iron oxohydroxide, is one of the most abundant iron oxide in the natural marine environment.
Phototransformation of ferric citrate in aquatic environment
Kolář, Michal ; Abida, O. ; Mailhot, G. ; Jirkovský, Jaromír ; Bolte, M.
Iron is the most abundant transition metal on the Earth. It is present in aquatic environments, soils as well as atmosphere. In the aquatic media, it is often presnt in a form of Fe(III) complexes, especially with polycarbolic acids. Citric acid was chosen as their suitable representative in this study.
Příprava a clastnosti TiO2 nanočástic a jejich kompositů
Paušová, Š. ; Mailhot, G. ; Prevot, V. ; Krýsa, J. ; Jirkovský, Jaromír
Práce pojednává o metodách přípravy TiO2 nanočástic a jejich vlastností a kompositů.
Physico-chemical properties and phototransformation of ferric citrate complex in aquatic environment
Kolář, Michal ; Abida, O. ; Mailhot, G. ; Jirkovský, Jaromír ; Bolte, M.
Iron is the most abundant transition metal on the Earth. It is present in aquatic environments, soils as well as atmosphere. In the aquatic media, it is often present ina form of Fe(III) complexes, especially with polycarboxylic acids.
Anisotropy of electrochemical properties of TiO2 (anatase in orientations (101) and (001)
Kavan, Ladislav
Application of TiO2 (anatase) as electrode material has been a subject of intense research in the past. For the fabrication of electrodes, macroscopic (mm-sized) single crystals were grown in two orientations with the exposed faces )101) or (001), resp.
