文摘

3D hierarchical α-Fe2O3 nanoparticles with different planes predominantly exposed were synthesized. The Cr(VI) removal ability reach to 34.4 mg/g by flower-like α-Fe2O3 particles with (0 0 1) plane exposed. The coordination between Cr(VI) and special doubly coordinated hydroxyl groups plays important role for adsorption.
