Developing a highly active and stable electrocatalyst for the oxygen evolution reaction (OER) is essential efficient hydrogen production through anion exchange membrane water electrolysis powered by renewable electricity. Recently, there has been renewed interest in designing electrocatalysts based on their work function optimization. The insights into materials' electronic properties gained from developing other heterogeneous catalysts, such as those used N2O decomposition, can be thus leveraged to enhance performance of OER electrocatalysts. Knowing that Bi enhances catalytic activity Co3O4 where surface play crucial role, we hypothesized it might also improve electroactivity electroactivity. Therefore, synthesized Bi-doped with different bismuth contents studied sample complementary set physicochemical, electrochemical, computational techniques. We found promoting atomically dispersed its electrocatalytic reducing energy potential-determining step improving electron charge transfer properties. Bismuth atoms enter octahedral sites Co3O4, creating centers enhancing vicinal Co OER. modified are characterized increased binding intermediate state metal–oxygen density states at Fermi level. former reduces overpotential required OER, whereas latter improves kinetics decreasing resistance.
