The adsorption performance of U （VI） over ZnO nanostructures with different fraction of polar facets was comparatively evaluated. Results indicate that the uniform flower - like ZnO dominated with { 001 } facets gives the maximum uranium adsorption capacity up to 2439 mg· g^-1 ,two times as much as the adsorption capacity of ZnO hexagonal rods with few { 001} facets. The thermodynamic analysis shows that the △H^0 is 33.78 kJ · mol^-1, and the AGO changes from -24.13kJ·mol^-1 to -28.67 kJ ·mol^-1 at 298 to 318K, indicating ...
