Efficacious visible-light photocatalytic degradation of toxics by using Sr2TiMnO6-rGO composite for the wastewater treatment
Sr2TiMnO6 (STMO) double perovskite was synthesized by a solid-state technique, and STMO-rGO (reduced graphene oxide) composite was prepared by a hydrothermal method. BET, XRD, XPS, TEM, SEM, and FT-IR techniques were used to investigate the properties and structures of the composite material. The ch...

description | Sr2TiMnO6 (STMO) double perovskite was synthesized by a solid-state technique, and STMO-rGO (reduced graphene oxide) composite was prepared by a hydrothermal method. BET, XRD, XPS, TEM, SEM, and FT-IR techniques were used to investigate the properties and structures of the composite material. The characterization results depict that this material is an extremely efficient catalyst, which shows an excellent photocatalytic activity. The material has a direct bandgap of 1.30 eV, which makes it suitable for the photocatalytic wastewater treatment. The photocatalytic efficiency of STMO-rGO powder was tested in Rhodamine B dye. The complete degradation of dye has occurred only in 5 min. The first-order kinetic reaction was observed in Visible light, whereas the second-order kinetic response observed in UV light. |
