Major Contributions
 

1. A hybrid MOF-COF membrane with fully sub-2 nm pore channels is fabricated, achieving simultaneous angstrom-level ion selectivity and strong acid resistance required for harsh osmotic energy harvesting environments.

2. The structural and chemical asymmetry of the MOF-COF architecture induces ionic current rectification, enabling the membrane to function as an ionic diode for directional ion transport without requiring geometric modification.

3. The sub-2 nm MOF-COF ionic diode membrane demonstrates high osmotic power density from ionic concentration gradients, surpassing conventional single-material membranes in both selectivity and stability.

主要貢獻
 

1. 製備出全孔道均小於 2 nm 的 MOF-COF 混合薄膜，同時實現亞埃級離子選擇性與強耐酸性，滿足惡劣滲透能收集環境的需求。

2. MOF-COF 架構的結構與化學不對稱性誘導離子電流整流，使薄膜無需幾何改性即可作為離子二極管實現定向離子傳輸。

3. 亞 2 nm MOF-COF 離子二極管薄膜從離子濃度梯度中展現高滲透功率密度，在選擇性與穩定性方面均優於傳統單材料薄膜。
