Prussian blue derived catalysts

Patent ·
OSTI ID:1892813

Prussian blue analog derived catalysts having a composition of highly porous transition metal (“TM”) oxides with nano particle size. Such OER catalysts are synthesized from the PBA, containing cobalt, iron, nickel, copper, manganese, zinc, magnesium etc., as secondary building units (“SBUs”) coordinated by hexacyano-based ligands. Furthermore, the PBA-derived catalysts may also integrated into a highly graphitized carbon network to further improve the conductivity, mass transport and durability against oxidative corrosion.
