Abstract

Sposób wytwarzania materiału o właściwościach fotokatalitycznych i biobójczych zawierającego zorientowane przestrzennie nanorurki ditlenku tytanu modyfikowanego metalami zwłaszcza szlachetnymi charakteryzuje się tym, że otrzymany materiał umieszcza się w atmosferze gazu obojętnego w wieloskładnikowym roztworze, który zawiera 30-50% wag. alkoholu jony i/lub nanocząstki jednego albo kilku metali, wybranych z grupy srebro, złoto, platyna, pallad, ruten, miedź, cynk, nikiel, rod, wolfram, kobalt, żelazo w ilości 0,05-5% wag. każdy oraz wodę. Wieloskładnikowy roztwór miesza się w warunkach ciemni przez 3-180 min.. Następnie prowadzi się naświetlanie za pomocą lampy emitującej promieniowanie UV przez 0,5-6 godz., suszy się w temperaturze 60-100°C przez 0,5-24 godz.. W odmianie wynalazku otrzymany materiał pokrywa się mikroemulsją W/O zawierającą ciekłe węglowodory, surfaktanty, jony i/lub nanocząstki jednego albo kilku metali, wybranych z grupy srebro, złoto, platyna, pallad, ruten, miedź, cynk, nikiel, rod, wolfram, kobalt, żelazo. Następnie pokrywa się mikroemulsją W/O zawierającą ciekłe węglowodory, surfaktanty oraz odczynnik redukujący, po czym suszy się w temperaturze 60-100°C przez 0,5-24 godz., a następnie kalcynuje się w temperaturze 250-750°C.
