Abstract

Hollow α-Fe₂O₃ urchin-like spheres were prepared by annealing the FeOOH precursor, which was synthesized via a template-free hydrothermal method. Interestingly, the size and hollowness of spheres could be tailored by adjusting the concentration of ferric sulphate. The sensing properties of the as-prepared samples were investigated.
