- •
The 3D ZnO shell was well-distributed on γ-Fe2O3 core in a controlled manner.
- •
The magnetic γ-Fe2O3@ZnO can be easily separated from solution.
- •
The photocatalyst exhibited enhanced activity under simulated sunlight irradiation.
- •
The separation of carriers was effectively accelerated by a type II heterostructure.
- •
The holes and hydroxyl radicals played major roles in ciprofloxacin degradation.
