A facile surfactant-free route to synthesize uniform Rb<sub>0.4</sub>M<sub>4</sub>[Fe(CN)<sub>6</sub>]<sub>2.8</sub>·7.2H<sub>2</sub>O (M = Co, Ni) hollow nanoparticles is described. Rb<sub>1.6</sub>Mn<sub>4</sub>[Fe(CN)<sub>6</sub>]<sub>3.2</sub>·4.8H<sub>2</sub>O serves as a sacrificial/removable core in the synthesis of core@shell heterostructures. After dissolution of the cores under very mild conditions, the crystalline hollow nanocubes feature well-defined micro-, meso-, and macropores. The surfactant-free approach preserves the reactivity of the Prussian blue analogue surface as evidenced by the subsequent synthesis of hollow shell@shell heterostructures
