Methylene blue elimination by magnetic ferric oxide-decorated and sulfonated sugarcane bagasse-derived porous carbon via catalysis Fenton reaction

Abstract

In this study, the magnetic ferric oxide-sulfonated porous carbon materials (Fe3O4-SPC) were fabricated using the magnetic ferric oxide (Fe3O4) nanoparticles via the sulfonation process with sugarcane bagasse as a main cellulose source. The characterization revealed that the spherical shape of Fe3O4 nanoparticles decorated on lamellar porous carbon sheet with uniform size less than 100 nm. Meanwhile, the catalytic assessment on the degradation of methylene blue via the Fenton reaction showed the ratio of Fe3O4:SPC = 1:2 obtaining the efficiency of 95% after 45 min. Moreover, the material had high reusability, retaining over 95% after 5 consecutive cycles.
