Structural and defect modulations of co-precipitation synthesized high-entropy Prussian blue analogue nanocubes via Cu/Zn co-doping for enhanced electrochemical performance

High entropy PBA is demonstrated for use as a supercapacitor electrode and an OER catalyst. Cu and Zn in the PBA tune the particle size, hexacyanoferrate vacancy content, specific surface area, electrical conductivity, and electronic structure.
