Bromide-mediated membraneless electrosynthesis of ethylene carbonate from CO₂ and ethylene.

ABSTRACT: Cyclic carbonates, such as ethylene carbonate, are crucial in various applications, including lithium-ion batteries and polymers. Traditional production routes for ethylene carbonate rely on high-temperature thermocatalytic processes that use fossil-fuel-derived epoxides and carbon dioxide (CO₂). Herein, we report a bromide-mediated membraneless electrosynthesis strategy for direction conversion of ethylene and CO₂ into ethylene carbonate. This method leverages electrolyte engineering to modulate the kinetics of solution chemistry to proceed at rates that match the high-current bromide electrooxidation, and cathode protection with chromium hydroxide film to suppress the parasitic bromine reduction reaction. These enable the system to operate at 10-250 mA/cm²
