Novel Prussian blue/natural porous framework nanocomposites (PB@Apple, PB@Corn stalk and PB@Pomelo peel) were successfully produced in aqueous solution via an in situ γ radiation method. They have layered porous structure with 70–100 nm irregular PB, regular polygonous porous structure with 50–70 nm cubic PB and hierarchical porous structure with 10–20 nm spherical PB, respectively. They exhibit good Cs+ adsorption properties and have maximal Cs+ adsorption capacities of 67.3, 62.1 and 83.8 mg g−1, which can be used to treat radioactive wastewater. This production method is simple, efficient and environmental-friendly.
