Surfactant-free hydrothermal synthesis of sub-10 nm γ-Fe2O3-polymer porous composites with high catalytic activity for reduction of nitroarenes.

Porous γ-Fe2O3-polymer composites were synthesized by a novel one-pot surfactant-free hydrothermal approach. The γ-Fe2O3-polymer composites consisting of 3.5 nm γ-Fe2O3 nanoparticles and porous polymers exhibited high catalytic activity and recycling performance in the reduction of nitroarenes.
