Experimental Considerations for Electrocatalytic CO2 Reduction

Electrocatalytic CO2 reduction offers the ability to store renewable energy in the form of carbon-based fuels. Currently this process suffers from poor activity and selectivity. Unfortunately the advances in electrocatalyst development are hampered by the poor reproducibility of experimental data, even for the most basic of electrocatalysts. Here, some of the possible underlying causes of this poor reproducibility are described and discussed with the intention of providing some insights into experimental procedures and considerations needed for robust experimental investigation of CO2 reduction.
