Abstract

The photo-Fenton properties of iron silicate composite materials were investigated by methylene blue dye degradation. From various iron oxide and iron silicate samples the best performing material, FeSiOx (bulk iron silicate) showed a first-order rate constant of (1.57 ± 0.04) × 10−2 min−1. According to the 57Fe Mossbauer spectra, XRD patterns and TEM images this sample showed the most amount of Fe2+ content in the form of Fe2SiO4 nanoprecipitations.
