Size-controlled synthesis of NiFe2O4 nanospheres via a PEG assisted hydrothermal route and their catalytic properties in oxidation of alcohols by periodic acid

- Hydrothermal synthesis of NiFe2O4 NPs with (C4H9)3N as hydroxylating agent.
- PEG 4000 was used as surfactant to control sizes of NPs.
- The TEM images revealed the material to be spherical in shape with sizes 2-10 nm.
- NiFe2O4 was used as recyclable catalyst for oxidation of alcohols by periodic acid.
