Is there any real advantage in co-electrolyzing CO2 and H2O in liquid phase to produce syngas versus using separated electrolysis of H2O and CO2?

Electrochemistry is a pathway to convert CO2 into valuable products such as CO. However, a potential side product in the cathode is H2. I wonder if it is possible to tune the composition of the...

I feel GCE is best option for acidic supporting electrolytes

Daniel Martín-Yerga

Maybe, it's because using CPE you don't have to worry about cleaning steps between measurements, you just do other electrode easily. A GCE is a tool that you need reutilize, then you need to clean very well between measurements (or applications).
