Influence of lattice strain on Fe₃O₄@carbon catalyst for the destruction of organic dye in polluted water using a combined adsorption and Fenton process.

ABSTRACT: In this study, 8, 25 and 50 wt% Fe₃O₄@activated carbon (AC) catalysts were prepared by simple coprecipitation method. The efficiency of the catalysts for the advanced Fenton's oxidation process using methylene blue (MB) as a model substrate was tested. Both modified and unmodified activated carbon catalysts exhibited similar activity towards the Fenton's oxidation process. Therefore, it is difficult to identify the role of the catalyst in this dye removal process. Hence, we proposed a new methodology to remove the MB by adopting the adsorption process initially, followed by the Fenton's oxidation process. The proposed process significantly improved the methylene blue decomposition reaction over the 25 wt% Fe₃O₄@AC catalyst. However, this trend wa
