Uniform urchin‐like α‐FeOOH hollow spheres assembled from nanoneedles have been synthesized via a facile and green one‐pot method. By simply adjusting the amount of glycerol in the reaction system, hierarchical urchin‐like α ‐FeOOH solid spheres or hollow spheres can be obtained. When evaluated for the potential use in water treatment, it is found that the as‐obtained uniform urchin‐like α ‐FeOOH hollow spheres exhibit excellent capability for removing both organic dye and heavy metal ions in waste water.
