ABSTRACT Prussian blue‐based nanoparticles (PBNPs) and related materials demonstrate extensive catalytic functions in both electrical and chemical reactions paired with water treatment and the conversion of energy. Their redox cycle between Fe 2+ and Fe 3+ works together along with their high surface area and adjustable electronic configuration to make them effective in catalyzing chemical transformations and saving energy. Prussian blue analogues (PBA) can be obtained by swapping the iron element present in the crystal structure of PB with a metal ion like Co, Mn and Ni without disintegrate in the crystal structure. In this review, multiple methodologies for the synthesis of PBNPs such as hydrothermal/solvothermal, double precursor, chemical precipitation, electrodeposition and reverse microemulsion is discussed. The catalytic potential of cobalt based, copper based, nickel based and other PBNPs for various organic transformations such as oxidation reactions, reduction reaction, Friedal craft acylation is reviewed in details.
