Acid blue 40 dye decolorization using magnetite nanoparticles with reduced graphene oxide and mesoporous silica as Fenton catalysts.

ABSTRACT: Synthetic dyes are predominantly emitted into the eco-environment resulting, in harmful effects on the environment and human. This study presents a new perspective on the mesoporous silica (SBA-16) and reduced graphene oxide (rGO) obtained from rice husk ash as substrates for Fe₃O₄ nanoparticles (NPs) to investigate their morphological and Fenton catalytic characteristics towards degradation of synthetic acid blue 40 dye (AB40). The adsorption and Fenton catalytic properties of AB40 dye by the prepared Fe₃O₄, Fe₃O₄/SBA-16 and Fe₃O₄/rGO catalysts were examined. The successful synthesis of such catalysts was affirmed by the results obtained from FE-SEM, EDX, TEM, FTIR, XRD and nitrogen adsorption measurem
