Novel hybrid nanostructures or nanocomposites are receiving increasing attention due to their newly evolved properties. In this work, α-Fe₂O₃ anchored to graphene oxide (GO) nanosheet (α-Fe₂O₃@GO) was synthesized through a facile hydrolysis process and its photo-catalytic performances and durability in heterogeneous Fenton system were fully evaluated. The decolorization rates of methylene blue in α-Fe₂O₃@GO + H₂O₂ + UV system within a wide pH range were approximately 2.9-fold that of classical Degussa P25 TiO₂ + UV and 2.4-fold that of α-Fe₂O₃ + H₂O₂ + UV. This enhanced decolorization of methylene blue (MB) in α-Fe₂O₃@GO + H₂O₂ + UV system were attributed to the unique incorporation of GO into the catalyst which not only mediated the morphology of active sites α-Fe₂O₃ nanoparticles but also offered high electron conductivity and electrostatic attraction between negatively charged GO …
