High entropy alloys mediated formation of multi-oxide nanoparticles on carbon fiber cloths and their synergistic effects in electrochemical performance

Abstract

A wet chemistry technique is developed to produce high entropy alloy nanoparticles on carbon fibers. Coatings display solution phase and can be aerially oxygenated into multi-oxides. Electrochemical measurements confirm the generation of high specific capacitance from multi-oxide coatings where individual components show redox reactions at different potentials thus producing large loops of charge–discharge. Comparative study confirms synergistic effects arising from individual oxides in coatings.
