Abstract

The invention provides a method for enhancing electricity production performance of a CO<2> mineralized battery by using riboflavin and the battery, and belongs to the technical field of CO<2> mineralization. The method is characterized in that a cation exchange membrane is placed in a CO<2> mineralized battery container, and the container is divided into a positive electrode region and a negativeelectrode region; a mixed solution of mirabilite and Ca(OH)<2> are added into the positive electrode region to serve as a positive electrode electrolyte; sodium bicarbonate is added into the negativeelectrode region to serve as a negative electrode electrolyte; meanwhile, a compound FMN is added into the negative electrode region to serve as a negative electrode electrocatalyst; and a direct current power source is applied between the positive electrode and the negative electrode. According to the invention, the compound FMN with PCET reaction property is adopted as the negative electrode electrocatalyst, and an ''H-organic'' intermediate body is formed in low potential to substitute H<2> to server as a circulating medium, so that high over-potential of HER and HOR reaction on the electrodes is avoided, and the electricity generating performance of the CO<2> mineralized battery can be greatly improved; and meanwhile, a noble metal Pt is not required to be used as a catalyst, so thatthe manufacturing cost of the CO<2> mineralized battery is lowered.
