Abstract:
Reduction of CO2 into useful fuels is regarded as a new way to deal with increasing CO2 emissions and its bad effects on climate. In this report, simple electrochemical oxidation-reduction method has been utilized to prepare Cu2O/polyaniline (PANI)/stainless steel composite electrode, which was identified as a contributor for CO2 reduction in an aqueous solution. X-ray diffraction (XRD), transmission electron microscope (TEM) and cyclic voltammetry technique were carried out to characterize the as-obtained electrode. As-synthesized composite electrode exhibited excellent electrocatalytic activity. The production of formaldehyde that comes from the reduction of CO2 using Cu2O/PANI/stainless steel based electrode (Cu2O/PANI/stainless steel) in 0.1 mol/L sodium sulfate solution is 0.505 μmol·L–1·h–1 approximately.
