Synthesis, structure and electrochemical performance of an ultra-high-entropy rare earth orthoferrite (UHE REO) for overall water splitting (OWS)

Using the two-step solution combustion method, nanocrystals of ultra-high-entropy rare-earth orthoferrite (UHE REO) were synthesized and used as effective catalysts for the hydrogen evolution reactions (HER) and oxygen evolutions (OER).
