Facile preparation of sphere-like copper ferrite nanostructures and their enhanced visible-light-induced photocatalytic conversion of benzene

- Spinel CuFe2O4 nanospheres were successfully synthesized via a facile method.
- CuFe2O4 nanospheres showed high photocatalytic activity toward benzene.
- Ethyl acetate, carboxylic acid and aldehyde were the intermediate products.
