Abstract Alternative energy sources are currently worldwide under development
to contribute to the increasing energy demand. Along with the introduction of new
technologies, heavy metals, such as radionuclides from nuclear power plant leaks,
might be released into the environment and contaminate waters, air, and soil. Among
the investigated methods, the use of adsorbents has been proven the most suitable
one, able to extensively remove heavy metals, e.g., radioactive
137
Cs
+
. Prussian blue
analogs (PBAs) have been demonstrated to be effective adsorbents toward the
sequestration of a variety of heavy metals, including the recovery and valorization
of rare earth elements. Here, we point out the structure-property link of PBAs: the
