Controlled growth of LaFeO3 nanoparticles on reduced graphene oxide for highly efficient photocatalysis

Using reduced graphene oxide (rGO) as a template and high temperature sol-gel chemistry, we have prepared LaFeO3 nanoparticles (NPs). The 15 nm LaFeO3 NPs have a bandgap of 1.86 eV and the LaFeO3-rGO can function as an efficient catalyst for degradation of methylene blue (MB) or Rhodamine B (RhB) un...

Description
Summary:Using reduced graphene oxide (rGO) as a template and high temperature sol-gel chemistry, we have prepared LaFeO3 nanoparticles (NPs). The 15 nm LaFeO3 NPs have a bandgap of 1.86 eV and the LaFeO3-rGO can function as an efficient catalyst for degradation of methylene blue (MB) or Rhodamine B (RhB) under visible-light irradiation with the electron transfer from the dye to hole dominating the oxidation process. The reported synthesis offers a general approach to perovskite-type NPs for efficient photocatalytic applications.
