B-site substitution in A <sub>2</sub> BO <sub>4</sub> Ruddlesden–Popper perovskites for enhanced OER and HER in alkaline medium

Ir substitution in Ir0.1 boosts bifunctional electrocatalysis by raising the O 2 2− /O − ratio, upshifting the d-band center, and increasing high-spin Co 3+ content, synergistically enhancing its activity.
