本研究は、炭素ドープしたグラファイト状窒化炭素（g-C3N4）光触媒を用いて、日焼け止め成分ベンゾフェノン-3（BP-3）を模擬海水中で効率的に分解し、サンゴの共生藻密度とサンゴ-藻類共生の回復を促進することを示した。触媒は海水環境で安定で、BP-3の分解速度は未修飾のg-C3N4と比べて約8倍向上し、分解中間体の生態リスクも低減した。固定化触媒構造により材料損失を抑え、サンゴの付着基盤としても機能する。海洋環境修復とサンゴ生態系回復のためのスケーラブルなアプローチを提案している。
English
This study presents a carbon-doped graphitic carbon nitride (g-C3N4) photocatalyst that efficiently degrades the UV filter benzophenone-3 (BP-3) in simulated seawater and promotes coral vitality recovery. The catalyst shows enhanced stability and an eightfold increase in BP-3 degradation rate compared to pristine g-C3N4, with reduced ecological risks of intermediates and significant recovery of zooxanthellae density and coral-algal symbiosis. Immobilized catalyst architectures minimize material loss and provide a substrate for coral attachment, offering a scalable approach for marine environmental remediation and coral ecosystem restoration.

📄 Abstract（原文）
Coral reefs, vital marine ecosystems, are increasingly threatened by global warming and chemical pollutants such as benzophenone-3 (BP-3), a widely used UV filter. To address this challenge, we present a carbon-doped graphitic carbon nitride (g-C3N4) photocatalyst with efficient singlet oxygen (1O2) generation for BP-3 degradation and coral vitality restoration under simulated seawater conditions. The photocatalyst exhibits improved stability and photocatalytic performance in complex seawater environments, with enhanced charge separation and an approximately eightfold increase in the apparent degradation rate of BP-3 compared with pristine g-C3N4. Toxicity assessments indicate reduced ecological risks of degradation intermediates and significant recovery of zooxanthellae density and coral–algal symbiosis. Immobilized catalyst architectures further minimize material loss and provide a suitable substrate for coral attachment. In this work, we demonstrate a seawater-stable, 1O2-driven photocatalytic strategy that enables efficient BP-3 removal and promotes coral vitality recovery, thereby offering a scalable approach for marine environmental remediation and coral ecosystem restoration. A carbon-rich photocatalyst enables efficient degradation of sunscreen pollutants in seawater while supporting coral vitality recovery through singlet oxygen generation.
