The research aims to explore syngas production through bipolar membrane electrolysis involving CO2 capture.
Utilized a bipolar membrane electrolyzer for bicarbonate electrolysis and formaldehyde oxidation.
Operated at a voltage of 1.7 V and current density of 200 mA cm −2.
Measured combined Faradaic efficiency of 200%.
Successfully produced syngas with a H2:CO ratio of 1.
Achieved a combined Faradaic efficiency of 200% during the process.
Abstract
A bipolar membrane electrolyzer coupling bicarbonate electrolysis with formaldehyde oxidation directly produces syngas (H 2 : CO = 1) at 1.7 V and 200 mA cm −2 with 200% combined Faradaic efficiency.
