<description>
<string language="fre"><![CDATA[The need for
novel membrane coated electrodes (MCE) for the electrochemical reduction of
carbon dioxide (CO2RR) may offer advantages in terms of control of reaction,
catalytic activity and stability of the electrode. The study of the
possibilities of mixed matrix membrane (MMM) overlayers with tuneable
ion-exchangeable, conductive and transport properties are essential targets for
the performance of the MCEs for electrochemical applications. The knowledge on
the effect of local pH and CO2 concentration diffusion to catalyst site, among
others, on the selectivity of the CO2 electroreduction to high
added-value products under alkaline conditions, especially when using Cu as
catalyst, is still scarce. The communication aims at evaluating the
relationship of the synthesis and morphological characterization of the MCEs
and the electrochemical characterization of novel based copper-containing MMMCE
with high CO2 permeability, chemical and mechanical stability in
alkaline solutions, on the performance, selectivity and stability of electrodes
in CO2RR. Cyclic voltammetry and electrochemical impedance spectroscopy will
give insight about the electrochemical behaviour pf MCEs in comparison with the
typically used gas diffusion electrodes (GDEs) prepared with commercial
ionomers. Preliminary electrolysis for the CO2RR will reveal the significant
impact of the presence of the polymeric membrane overlayer on the efficiency
and selectivity of CO2RR.
