Abstract | CeO2 micro/nanospheres with perfect spherical morphology, large specific surface area, high porosity, high stability and adjustable diameter were hydrothermally synthesized from a simple system, and the stirring-time before hydrothermal process was found to be the key factor for the final particle size control. The CeO2 spheres with diameters from ∼800 nm to ∼50 nm could be harvested by controllable synthesis. And the highest specific surface area of these CeO2 spheres could achieve 182 m2 g-1. Moreover, CeO2 spheres with higher specific surface areas (182 m2 g-1 and 117 m2 g-1) showed excellent performance in removal of heavy metal ion Cr(VI) from the aqueous solution. The Cr(VI) removal efficiencies could reach up to 94%. |
