In this article, Fe-doped carbon aerogels from sodium alginate were used for the removal of methylene blue (MB) in water. Under acidic condition, the sample carbonized at 700 °C (T700) undergoes Fe-C micro-electrolysis to produce highly chemically active Fe2+ and [H] to degrade MB. Under neutral or alkaline conditions, Fe2+ produced by Fe-C micro-electrolysis become Fe(OH)3, which can effectively adsorb MB. In addition, when T700 combines with H2O2 to form Fenton system, the MB removal efficiency was significantly improved. The Fe-doped carbon aerogels can be used in wastewater treatment and when combine the materials with H2O2 can greatly improve the MB removal efficiency.
