A method for efficient electrocatalytic synthesis of pure liquid product solutions including h2o2, oxygenates, ammonia, and so on

A process for producing high purity and concentrated liquid products through electrocatalytic reaction in an electrosynthesis cell comprising:

• a cathode compartment including a cathode electrode comprising a gas diffusion layer loaded with a selective electrocatalyst for selective reduction reactions;
• an anode compartment including an anode electrode comprising a gas diffusion layer loaded with a catalyst for oxidation reactions;
• a solid electrolyte compartment comprising a porous solid electrolyte, an inlet, and an outlet;
• a cation exchange membrane;
• and
• an anion exchange membrane;
• wherein a hydrogen gas or water solutions are supplied to the anode to be electrochemically oxidized on the oxidation reaction catalysts;
• an oxygen, CO2, CO, or N2 containing gas is supplied to the cathode to be selectively reduced by the selective reduction reaction catalyst;
• wherein the solid electrolyte compartment is separated from the cathode and the anode by the anion exchange membrane and the cation exchange membrane and deionized water or N2 gas is supplied to an inlet of the solid electrolyte compartment to flow through the porous solid electrolyte to bring out the generated liquid product.
