Electron transfer in saline is crucial for electricity supply, energy storage, and catalysis. By dispersing nanoporous coordination polymer into seawater, porous fluid can be generated to mediate electron transfer between solid donor and dissolved oxygen. Key factors in accelerating electron transfer include dynamic fluid conditions, porous electrode, and connection between porous seawater and environmental air.
Electron transfer between solid and gas phases in saline is of vital importance to electricity supply, energy storage and conversion, and catalysis. In most cases, seawater does not contribute greatly to the electron transfer process. Here we report a strategy to generate porous fluid by dispersing nanoporous coordination polymer into the seawater. In situ ultraviolet-visible and electrochemical spectroscopy confirms that the porous seawater fluid mediates electron transfer between the solid donor and the dissolved oxygen The key factors in accelerating electron transfer are found to be (1) the porous electrode, (2) the connection between the porous seawater and the environmental air, and (3) the dynamic condition of the fluid Enhanced electron transfer between the alloy and the dissolved oxygen leads to an efficient ocean electricity supply strategy based on the porous seawater fluid.
