Major Contributions
1. Atomic layer graphene (ALG) serves dual functions as a charge transport interlayer and catalytic interface, enabling the iodide oxidation reaction (IOR) as a thermodynamically favorable alternative anode reaction to OER in photoelectrochemical (PEC) seawater splitting.
2. The lower thermodynamic potential of IOR coupled with ALG-modified photoanodes enables bias-free PEC operation, overcoming the large external bias requirement that limits conventional PEC water splitting systems.
3. ALG integration significantly improves photocurrent density, charge separation efficiency, and long-term operational stability under realistic seawater conditions, establishing a dual-functional graphene strategy for solar-driven hydrogen production.
主要貢獻
1. 原子層石墨烯（ALG）發揮電荷傳輸夾層與催化界面的雙重功能，使碘化物氧化反應（IOR）成為光電化學（PEC）海水分解中熱力學上有利的替代陽極反應，取代析氧反應。
2. IOR 較低的熱力學電位結合 ALG 改性光陽極實現無偏壓 PEC 操作，克服限制傳統 PEC 水分解體系的大外加偏壓需求。
3. ALG 整合顯著改善真實海水條件下的光電流密度、電荷分離效率與長期操作穩定性，確立雙功能石墨烯策略用於太陽能驅動產氫。
