Fe₂O₃/Mn₂O₃ nanoparticles: Preparations and applications in the photocatalytic degradation of phenol and parathion in water

Abstract

Abstract In this study, nanoparticles of Fe 2 O 3 /Mn 2 O 3 mixture were obtained using the sol–gel method. The synthesis uses the combination of polyvinyl alcohol (PVA) and tartaric acid (TA). Synthesized catalysts prove superior compared to those afforded from previous reports. To be specific, desired catalysts can be received at lower calcination temperature. Furthermore, their structures display higher uniformity in term of particle sizes. Finally, they show better performance for the photocatalytic degradation of model‐persistent organic compounds.
