Spin Matters: A Multidisciplinary Roadmap to Understanding Spin Effects in Oxygen Evolution Reaction During Water Electrolysis (Adv. Energy Mater. 4/2026)

Water Electrolysis Understanding spin-dependent enhancement of the oxygen evolution reaction (OER) is critical for advancing hydrogen-based green energy systems. This roadmap outlines a combination of experiments, operando techniques, and computational modelling to elucidate the mechanisms underlying chiral-induced spin selectivity and magnetic effects that contribute to spin-enhanced OER. By establishing a conceptual framework and highlighting key knowledge gaps, it aims to accelerate the development of next-generation water-splitting catalysts.
