AI Article Synopsis
- * Researchers created a Janus metal-organic framework (J-MOF) membrane using an electrodeposition technique, which allows for quick ion transport and excellent ion selectivity.
- * The J-MOF's design, with its asymmetric structure, effectively minimizes ion concentration polarization and boosts charge separation, resulting in a notable output power density of 3.44 W/m at a high concentration gradient.
Article Abstract
The unique ion-transport properties in nanoconfined pores enable nanofluidic devices with great potential in harvesting osmotic energy. The energy conversion performance could be significantly improved by the precise regulation of the "permeability-selectivity" trade-off and the ion concentration polarization effect. Here, we take the advantage of electrodeposition technique to fabricate a Janus metal-organic framework (J-MOF) membrane that possesses rapid ion-transport capability and impeccable ion selectivity. The asymmetric structure and asymmetric surface charge distribution of the J-MOF device can suppress the ion concentration polarization effect and enhance the ion charge separation, exhibiting an improved energy harvesting performance. An output power density of 3.44 W/m has been achieved with the J-MOF membrane at a 1000-fold concentration gradient. This work provides a new strategy for fabricating high-performance energy-harvesting devices.
