Abstract
Cilj rada bio je sintetizirati cinkov oksid karakteristične listićave strukture hidrotermalnom metodom te ispitati njegovu fotokatalitičku aktivnost. Ispitivan je utjecaj različitih čimbenika sinteze cinkova oksida na strukturu krajnjeg produkta: temperature i vremena sinteze, te koncentracije tvari u polaznoj otopini. Iz polazne vodene otopine cinkova acetata uz dodatak heksametilentetramina (HMTA) i natrijeva citrata uspješno su sintetizirani slojevi listićave strukture, čija je struktura sačuvana i nakon žarenja kojim su slojevi prevedeni u ZnO. Otopina bez dodatka HMTA također je dala hijerarhijsku strukturu, ali sinteza nije bila ponovljiva u većem volumenu. Ispitivanjem fotokatalitičke aktivnosti pripravljenih slojeva ZnO utvrđeno je da pokazuju fotoaktivnost, sličnu kao cinkov oksid dobiven postupkom kemijske depozicije iz metanolne otopine čija je fotokatalitička aktivnost utvrđena u ranijem istraživanju.
Abstract (english)
Purpose of this paper was to synthesize zinc oxide with characteristic layered structure by hydrothermal synthesis and evaluate its photocatalytic activity. During the synthesis of zinc oxide, the influence of various factors on the final product structure, such as temperature and time of synthesis, as well as the concentration of the substance in the starting solution were examined. From the starting aqueous solution of zinc acetate with the addition of hexamethylenetetramine (HMTA) and sodium citrate, the layered structure was successfully synthesized. Layered structure of zinc oxide coatings was preserved during the annealing process. The solution without the addition of HMTA also gave a hierarchical structure, but the synthesis was not repeatable at greater volume. By testing photocatalytic activity, it has been found that hydrothermally synthesized zinc oxide shows photoactivity, similar to zinc oxide obtained by a chemical bath deposition process whose photocatalytic activity was determined in an earlier study.
