二維金屬有機骨架奈米複合薄膜之縮短離子傳輸路徑用於提升鹽度梯度能量收集
Major Contributions
1. Development of an innovative Cu-TCPP@SNF nanocomposite membrane that combines 2D metal-organic frameworks (Cu-TCPP) with silk nanofibers (SNFs), achieving remarkable stability in electrolyte solutions and enhanced ion transport efficiency through shortened ion pathways.
2. Achievement of exceptional power density performance, reaching ~29.5 W/m² under a 5M/0.01M NaCl gradient, surpassing existing advanced membranes, and demonstrating stable operation for over a week in high-concentration saline solutions.
3. Creation of a unique membrane structure featuring abundant one-dimensional ion pathways across the membrane while maintaining minimal layer separation, resulting in lower membrane resistance and higher ion permeability compared to conventional 2D lamellar membranes.
主要貢獻
1. 開發創新的Cu-TCPP@SNF奈米複合薄膜,結合二維金屬有機骨架(Cu-TCPP)與絲蛋白奈米纖維(SNFs),實現在電解質溶液中的卓越穩定性,並通過縮短離子傳輸路徑提高離子傳輸效率。
2. 達到優異的功率密度表現,在5M/0.01M氯化鈉梯度下可達~29.5 W/m²,超越現有先進薄膜,並在高濃度鹽溶液中展現超過一週的穩定運作。
3. 創造獨特的薄膜結構,具有豐富的一維離子傳輸通道,同時保持最小層間距離,相較於傳統二維層狀薄膜,實現更低的薄膜電阻和更高的離子滲透性。
