Abstract

While it is well recognized that mass transfer is an important factor in electrochemical reactions, the influence of mass transfer, especially of the convection on the electrochemical CO2 reduction has not been investigated. In this study, we focused on the influence of convection in a flow cell system using a boron-doped diamond electrode. The results clearly showed that convection improved the product selectivity and electrode potentials in CO2 reduction. It suggested that convection controls CO2 mass transfer in a flow cell system and influences the reactivity of electrochemical CO2 reduction.
