1Productivity
If CO2 is blown into seawater to lower pH for electrolysis, then synthetic gas can be produced, but production efficiency is poor due to low solubility of CO2 in water
Solution Approach 1:
The invention changes the chemical environment at the electrode surface by introducing a solid base additive, creating a localized high pH region that enhances CO2 solubility and promotes CO2 reduction reaction, thereby improving synthetic gas production efficiency despite the overall low solubility of CO2 in water
Solution Approach 2:
The solid base additive is provided at least on the electrode material, creating a localized basic environment specifically at the reaction site where CO2 reduction occurs. This local pH modification enhances CO2 adsorption and reaction efficiency without requiring bulk pH adjustment of the entire electrolyte solution
