چکیده
Abstract In this present study, a novel method to fabricate bimetallic Fe-Co catalyst supported on waste silica was investigated for the photo-Fenton-like (PFL) degradation of Methylene Blue (MB) dye. The uniqueness work is preparation via fluidized-bed crystallization (FBC) process. Under optimum conditions initial pH 3.0, 3.0 mM H 2 O , and 1.0 g L -1 FBC-derived Fe-Co/SiO (fFCS), maximum response decoloration mineralization efficiencies 20 mg MB in 60 min were 100 65%, respectively. Compared impregnated catalyst, fFCS exhibited comparable efficiencies, relatively lower metal leaching both iron cobalt. Superoxide radical unveiled be dominant reactive oxygen species PFL system over catalyst. catalysts characterized by Fourier Transform Infrared spectroscopy, Energy Dispersive X-ray spectroscopy Scanning Electron Microscopy. results show successful incorporation cobalt surface SiO support material.
