  • Framework Mn in mesostructured silicate as catalyst for the decomposition of organic dye [Elektronski vir]
    Maučec, Darja ...
    Among a wide range of organic pollutants detected in industrial and municipal wastewater, dyes are an important group. An attractive, sludge free alternative for the treatment of dyes in wastewater, ... is the use of advance oxidation processes (AOPs). Hydroxyl radicals ( OH), highly reactive species generated in sufficient quantities by AOPs, have ability to decompose dyes. Most of AOPs use a combination of strong oxidizing agents (e.g. H2O2, O3) with catalysts (e.g. transition metal ions) and irradiation (e.g. ultraviolet and visible light). The current study reports a green decomposition of methylene blue, in industry the most important basic cationicdye, by advanced oxidation method (AOP) using H2O2 as the oxidant and mesostructured silicate MnKIL-2 with framework manganese as heterogeneous catalyst. The KIL family is related to mesostructured silicate families with interparticle (textural) porosity (HMS, MSU, NBS). Manganese is known as one of the most intensively used elements to promote redox catalysis.
