Abstract

Područje heterogene fotokatalize istražuje primjenu fotokatalizatora, često u obliku čvrstih materijala, kako bi se potaknule kemijske reakcije pod utjecajem svjetlosti. Cilj ovog preglednog rada bio je ocijeniti učinkovitost fotokatalizatora u razgradnji onečišćivala u vodi te pružiti bolji uvid u mehanizme reakcija i utjecaj različitih parametara na procese fotorazgradnje. Glavnina istraživanja proširen je na optimiranje procesa sinteze heterogenih fotokatalizatora, s posebnim naglaskom na primjene TiO2 fotokatalizatora vezanog na perlitnom nosaču. Kroz upotrebu različitih tehnika karakterizacije, istraživane su strukturne karakteristike fotokatalizatora, uključujući morfologiju, kristalnu strukturu te površinska i optička svojstva. Istraživanje značajno pridonosi produbljenom razumijevanju mehanizama fotokatalitičkih reakcija, pružajući smjernice za unapređenje učinkovitosti ovih procesa.

Abstract (english)

In the field of heterogeneous photocatalysis, the use of photocatalysts, often in the form of solid materials, to initiate chemical reactions under the influence of light is being explored. The aim of this review was to evaluate the efficiency of photocatalysts in the degradation of pollutants in water and to provide a better understanding of the reaction mechanisms and the influence of different parameters on photocatalytic degradation processes. The main part of the research was extended to the optimization of the synthesis of heterogeneous photocatalysts, with a particular focus on the application of TiO2 photocatalysts immobilized on perlite supports. Through the use of various characterization techniques, the structural features of the photocatalysts have been investigated, including morphology, crystal structure, and surface and optical properties. This research contributes significantly to a deeper understanding of photocatalytic reaction mechanisms and provides insights to improve the efficiency of these processes.
