Abstract
Sposób otrzymywania fotokatalizatora na bazie TiO2 aktywnego w świetle widzialnym, modyfikowanego węglanem guanidyny charakteryzuje się tym, że mieszaninę uwodnionego amorficznego TiO2 - kwasu metatytanowego oraz węglanu guanidyny poddaje się prażeniu w temperaturze 700 - 900°C, w atmosferze beztlenowej uzyskanej z użyciem gazów inertnych, przy czym stosunek masowy azotu do TiO2 wynosi od 0,5:9,5 do 2:8. Jako gaz inertny stosuje się argon. Stosunek anatazu do rutylu w otrzymanym fotokatalizatorze wynosi od 90:10 do 1:99. Ujawniono też zastosowanie katalizatora do fotokatalitycznego rozkładu i mineralizacji związków organicznych w wodzie, zwłaszcza diklofenaku lub kwasu octowego, w obecności promieniowania VIS i UV.The method of obtaining a photocatalyst based on visible active TiO2, modified with guanidine carbonate is characterized by the fact that the mixture of hydrated amorphous TiO2 - metatitanic acid and guanidine carbonate is calcined at a temperature of 700 - 900 ° C, in an anaerobic atmosphere obtained using inert gases, using where the mass ratio of nitrogen to TiO2 is 0.5: 9.5 to 2: 8. Argon is used as inert gas. The ratio of anatase to rutile in the obtained photocatalyst is from 90:10 to 1:99. The use of a catalyst for photocatalytic decomposition and mineralization of organic compounds in water, especially diclofenac or acetic acid, in the presence of VIS and UV radiation has also been disclosed.
