Abstract

Przedmiotem zgłoszenia jest sposób otrzymywania materiału fotoaktywnego na bazie modyfikowanych nanorurek ditlenku tytanu, który charakteryzuje się tym, że na wodorowanych nanorurkach ditlenku tytanu poddaje się potencjostatycznej elektropolimeryzacji 3,4-etylenodioksytiofen, przy czym proces elektropolimeryzacji prowadzi się w wodnym roztworze 3,4-etylenodioksytiofenu o stężeniu 0,08 - 0,015 M, w obecności jonów Fe(CN)63-/4- o stężeniu 0,01 M - 0,1 M, przy gęstości ładunku w zakresie 20 - 150 mC/cm2 oraz przy potencjale anodowym w przedziale 1-1,6 V względem elektrody Ag/AgCl(0,1 M KCl). Następnie otrzymany materiał elektrodowy poddaje się procesowi restrukturyzacji, który prowadzi się na drodze polaryzacji potencjodynamicznej w roztworze FeCl3 o stężeniu w zakresie 0,01 M - 0,5 M, w zakresie potencjałów -0,4 V - 0,9 V względem elektrody Ag/AgCl(0,1 M KCl). Uzyskany materiał elektrodowy poddaje się procesowi pirolizy w przedziale temperatur od 300 do 500°C w atmosferze powietrza przez 3 - 5 godzin.The subject of the application is a method of obtaining a photoactive material based on modified titanium dioxide nanotubes, which is characterized by the fact that on hydrogenated titanium dioxide nanotubes, 3,4-ethylenedioxythiophene electrostolymerization is subjected to potentiostatic electropolymerization, while the electropolymerization process is carried out in an aqueous solution of 3,4-ethylenedioxythiophene concentration 0.08 - 0.015 M, in the presence of Fe (CN) 63- / 4- ions at a concentration of 0.01 M - 0.1 M, with a charge density in the range 20 - 150 mC / cm2 and anode potential in the range of 1 -1.6 V relative to an Ag / AgCl electrode (0.1 M KCl). Then, the obtained electrode material is subjected to a restructuring process, which is carried out by potentiodynamic polarization in a solution of FeCl3 with a concentration in the range of 0.01 M - 0.5 M, in the potential range -0.4 V - 0.9 V in relation to the electrode Ag / AgCl (0.1 M KCl). The obtained electrode material is subjected to a pyrolysis process in the temperature range from 300 to 500 ° C in an air atmosphere for 3 - 5 hours.
