Abstract
To enhance H₂ evolution via water splitting, preventing deep electron traps—-often formed by anion vacancies—-is essential. Transient IR absorption spectroscopy reveals that 2D layered materials like Bi₄NbOCl rarely form such traps. This is due to the formation of a defect-tolerant, bonding-based conduction band minimum, which effectively suppresses deep traps while maintaining high electron reactivity. Addressing this issue has been a major focus in photocatalysis research, as reported by Akira Yamakata, Takafumi Ogawa, and Hiroshi Kageyama et al. in their Research Article (e202419624).
