| 英文摘要 | alpha-Fe2O3 nanoparticles with different morphologies, such as hollow spheres, nanotubes with a limited amount of the {0001} plane exposed, and nanoplates and nanorings with the {0001} plane predominantly exposed, have been synthesised by using NaH2PO4 and urea in a facile hydrothermal method. The mechanism of the morphology evolution from hollow sphere to nanoring has been investigated. It is proposed that the polymerisation of Fe3+/H2PO4- plays an important role in the formation of these morphologies. The adsorption of Cr(VI) from aqueous solution onto these alpha-Fe2O3 nanoparticles showed that the alpha-Fe2O3 with nanoring morphology has the highest removal efficiency, and the adsorption capacity reached 16.9 mg g(-1). These results indicate that the adsorption mechanism of Cr(VI) onto hematite nanoparticles is a chemisorption process through doubly and triply coordinated hydroxyl groups on the outer surface of alpha-Fe2O3. |
