Abstract
U radu je provedena modifikacija letećeg pepela (FA4) klorovodičnom kiselinom, koji je potom korišten kao nosač TiO2 fotokatalizatora. Za istraživanje fotokatalitičkog procesa pročišćavanja otpadnih voda s fotokatalizatorom titanijeva oksida (TiO2) provedeno je istraživanje uvjeta njegove sol-gel sinteze kao i modifikacija njegova sastava. Tijekom sinteze dodane su nanočestice TiO2 u udjelu od 1 mas% i 3 mas % te je variran udio letećeg pepela u iznosu od 16 mas% i 20 mas%. Sintetizirano je pet različitih uzoraka fotokatalizatora titanijeva oksida koji su karakterizirani rendgensko difrakcijskom analizom (X-ray), skenirajućom elektronskom mikroskopijom (SEM) te je provedena njihova fotokatalitička validacija UV/VIS spektrofotometrom. Iz rezultata fotokatalitičke aktivnosti vidljivo je da najveću fotokatalitičku aktivnost ima čisti sintetizirani uzorak TiO2, a nakon 60 minuta procesa fotorazgradnje reaktiv red bojila (RR45) uzorci FA4/16-TiB i FA4/16-TiB-1 pokazuju jednaku ili neznatno veću fotokatalitičku efikasnost.
Abstract (english)
In this paper modification of flying ash (FA4) with hydrochloric acid was performed, which is then used as carrier of TiO2 photocatalyst. Further in the research of sol-gel synthesis conditions of titanium dioxide (TiO2) and its modification in composition was carried out in order to study photocatalytic process of wastewater treatment. During the synthesis in some samples TiO2 nanoparticles are added in a fraction of 1 wt% and 3 wt%, and the fraction of fly ash was varied in the amount of 16 wt% and 20 wt%. Five different samples of the photocatalyst titanium oxide was synthesized, which were characterized by X-ray diffraction analysis, scanning electron microscopy (SEM) and their photocatalytic validation was performed with UV/VIS spectrophotometer. From the results of the photocatalytic activity it is evident that the highest photocatalytic activity has the pure synthesized sample TiO2, while after 60 minutes the photodegradation of reactive red dyes (RR45) show the same or slightly higher photocatalytic efficiency for the samples FA4 /16-TiB and FA4 /16-TiB-1.
