Benzotriazole-based ionic COFs embedded in biologic aerogels for stable photocatalytic seawater splitting

Key Points

• The aim is to evaluate the photocatalytic efficiency of benzotriazole-based ionic COFs in seawater splitting.
• Benzotriazole-based ionic COF synthesized via post-modification.
• COF embedded into a nanocellulose-supported aerogel.
• Performance measured in terms of hydrogen evolution rate (HER) and apparent quantum yield (AQY).
• Achieved HER of 87 mmol m−2 h−1.
• Measured AQY of 11.6% at 420 nm.
