Abstract | Macro/nano-composite CeO2 spheres with variable diameters of 30-300 μm assembled from nanoparticles of 5-8 nm were synthesized through the calcination of the well assembled spherical Ce(COOH)3 precursor. The controlled hydrolysis of DMF is the key factor for both the crystallization of Ce(COOH)3 and the formation of its macrospheres. These hierarchical CeO2 macrospheres possess pretty high specific surface areas of up to ∼190 m2 g-1 and show an excellent ability to remove Cr(vi) from aqueous solution. Moreover, when substituted with Bi(iii), the oxygen storage capacity (OSC) of these CeO2 spheres could be improved sharply to 3243.75 μmol [O] g-1. With an easy-to-manipulate macroscale spherical morphology, these materials are easily recycled. This synthesis opens a promising route for high performance metal oxides. |
