Electrochemical Conversion of CO2 into Useful Chemicals and PKL Electricity

Abstract

AbstractA study has been conducted on the electrochemical conversion of CO2 into useful chemicals and PKL electricity. The experimental technique of CO2 production device for use in the electrochemical cell is found. Here, the chemical reaction is NaHCO3 + HCl = NaCl + H2O + CO2. The produced CO2 goes out through a tube. It is also found that the produced CO2 was supplied to a PKL Electrochemical cell for getting electricity for a long time duration. It is also found that the pH level of PKL extract remains almost constant during electricity generation. The produced CO2 is mixed with the H+ and formed HCO3, which maintains the constant pH level of the PKL extract during PKL electricity generation. Using this technique, the performance of PKL electrochemical cell has been studied. A comparative study has also been conducted between CO2-based and non-CO2-based PKL electrochemical cells. The studied parameters are self-discharge capacity, discharge capacity with load, internal resistance, etc. Mallic acid increased during night time. Performances are better in the night time for collected PKL than the day time collected PKL. Reactant ion (H+) increases in the night time. Cell voltage (Ecell) increases in the night time. The pH of the PKL extract decreases in the night time. This type of work has not been done before yet all over the world. This work will help in the sustainable PKL electricity generation in near future.KeywordsCO2 productionElectrochemical conversionPKL electricityUseful chemicalsCO2-based PKL electrochemical cellGalvanic cell
