摘要： The present disclosure relates to an electrochemical method for converting captured CO2 into formate (HCOO−). This method involves capturing waste CO2 by co-absorption of the waste CO2 with green ammonia (NH3) to form ammonium bicarbonate (NH4HCO3) and converting the ammonium bicarbonate (NH4HCO3) into formate (HCOO−), wherein said converting is carried out in an integrated flow electrolyzer system. Another aspect of the present disclosure relates to an integrated flow electrolyzer system comprising an alkaline electrolyzer for producing green NH3 from NO3−, an NH3—CO2 absorbing unit whereby waste CO2 is co-absorbed with ammonia (NH3) to form ammonium bicarbonate (NH4HCO3), and a bicarbonate electrolyzer for converting the ammonium bicarbonate (NH4HCO3) into formate (HCOO−).
