Advanced Science, Volume 13, Issue 1, 5 January 2026.A sodium‐metalated, nitrogen‐rich carbon nitride (PH‐C3N5‐Na) is developed to generate solvated electrons (SEs) under visible‐light irradiation via a eutectic NaCl/LiCl molten salt‐assisted method. The in situ generated SEs drive a stepwise oxygen reduction via •O2−. Thus, an exceptional quantum efficiency of 54.4% (420 nm) is achieved.
