WebNov 10, 2024 · As covalency is increased even further (e.g., Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3–δ), perovskites become unstable [converting to amorphous (oxy)hydroxides] under OER (75, 76). As a result, an optimum covalency, as measured by the O 2p-band center, gives rise to both high activity and stability, which is the case for Pr 0.5 Ba 0.5 CoO 3–δ .
