Monodisperse Zn ferrite hollow nanospheres and nanosheets could be selectively synthesized via a facile solvothermal method. The shape, structure and size of Zn ferrites were investigated by XRD, TEM, SEM, and HRTEM. The magnetic and microwave absorption properties of hollow Zn ferrite nanospheres and nanosheets were also investigated in detail. Magnetic studies revealed that both the saturation magnetization (<i>M</i><sub>s</sub>) and coercivity (<i>H</i><sub>c</sub>) of hollow nanospheres are drastically higher than those of nanosheets. Electromagnetic and resulting microwave adsorption properties showed that hollow nanospheres have four dips and the maximum magnitudes of the dips is −31.44 dB at 10.48 GHz. The probable formation mechanism of hollow nanospheres was discussed on the basis of the experimental results.
