Nanoheterostructures based on nanosized Prussian blue and its Analogues: Design, properties and applications

Nanoheterostructures combining Prussian blue (PB) or Prussian blue analogues (PBA) coordination polymers with other inorganic materials onto a single nanosystem are a highly challenging and rapidly emerging class of discrete hybrid multifunctional nano-objects, where chemical and physical properties can act separately or in synergy. They present various morphologies and chemical compositions, including diverse combinations of nanosized PB(A)s with metals, metal oxides, luminescent Ln3+-based fluorides or Ln3+-doped nanoparticles, semiconductors, silica, carbon nanotubes, metal–organic frameworks and others. Here, we present an overview focusing on relevant progresses achieved in this family of nanomaterials, giving an emphasis on their topology, physical and chemical properties as well as applications highlighting the role and contribution of the nano-sized PB(A)s.
