This work aims to enhance the efficiency of CO2 reduction through innovative catalyst and reactor designs.
Developed alkaline microflow electrolytic cells using cobalt phthalocyanine and SnO2 as catalysts.
Measured Faradaic efficiency and partial current density at different overpotentials.
Investigated the role of alkaline electrolytes in reducing overpotential.
CO-selective cell achieved a Faradaic efficiency of 94% and a partial current density of 31 mA/cm2 at a 0.56 V overpotential.
HCOO–-selective cell reached a Faradaic efficiency of 82% and a partial current density of 113 mA/cm2 at a 1.36 V overpotential.
Reduced overpotential attributed to a pH gradient near the cathode surface.
