The ocean serves as a vital CO2 sink, with over 100 times the CO₂ concentration of the atmosphere, making direct removal from seawater more efficient. This project, Direct Ocean Electrocapture (DOE), aims to utilize electrcity to extract CO₂ from seawater using a novel material designed as a "CO₂ sponge". Metal-organic frameworks (MOFs) are promising candidates for this application, and MOF with high bicarbonate (CO2 equivalent in ocean) affinity for DOE will be developed.
