“…Thus, it is imperative to develop novel, efficient and friendly materials and technologies to remove these contaminants. A number of iron oxides including goethite [2,3], hematite [4,5], magnetite [6,7], ferrihydrite [8,9] and lepidocrocite [10,11] were applied to adsorb heavy metal species and initiate the advanced oxidation processes (AOPs) as heterogeneous catalysts for organic degradation.…”

h i g h l i g h t s• Ak/rGO was successfully prepared by co-precipitating and reduction processes.• Fe O C band inhabited the reduction of graphene oxide.• Degradation rate of 2-chlorophenol for Ak/rGO increased 2-5 times than that for Ak.• Higher removal rate is due to the syn- In this work, the composite of reduced graphene oxide and akageneite (Ak/rGO) was synthesised by co-precipitating and reduction processes. The morphological and structural features of the synthesized composites (Ak/rGO) were characterized by XRD, SEM, BET, FTIR, Zeta potential and XPS. The results revealed that (1) beta-FeOOH was successfully loaded on the reduced graphene oxide (rGO); (2) the presence of strong interfacial interactions (Fe O C bonds) between rGO and beta-FeOOH was observed; (3) the reduction of graphene oxide may be inhabited in the formation process of beta-FeOOH, producing rGO sheets rather than rGO sphere. In the heterogeneous Fenton-like reaction, the degradation rate constants of 2-chlorophenol (2-CP) increased 2-5 times after the addition of rGO probably due to the Fe O C bond. The increase of the content of rGO could contribute to the removal of 2-CP, due to the synergy of catalysis and 2-CP adsorption towards Ak/rGO. In this study, the Ak/rGO composite has exhibited great potential and significant prospects for environmental application.

“…Therefore, secondary reactions do not affect rate reaction. The constant reaction rate using iron hidride was ten times higher at pH = 3 than at pH = 8 (Barreiro et al, 2007). Reaction rate constants were determined at 0,24−2,83.…”
