Abstract:Acidic seawater electrolysis offers significant advantages in high efficiency and sustainable hydrogen production. However, in situ electrolysis of acidic seawater remains a challenge. Herein, a stable and efficient catalyst (SPTTPAB/IrO2) is developed by coating iridium oxide (IrO2) with a microporous conjugated organic framework functionalized with sulfonate groups (‐SO3H) to tackle these challenges. The SPTTPAB/IrO2 presents a ‐SO3H concentration of 5.62 × 10−4 mol g−1 and micropore below 2 nm numbering 1.0… Show more
