Hierarchical CeO2 nanospheres as highly-efficient adsorbents for dye removal
Abstract
Herein, we reported a facile electrochemical method to prepare hierarchical porous CeO2 nanospheres and their implementation as highly-efficient absorbents in removing organic dyes. These hierarchical CeO2 nanospheres constructed of numerous nanocrystallites exhibit excellent performance in removing Congo red. The adsorption capacity at 60 min reached 942.7 mg gā1.
