Understanding Selectivity Control in the Electrocatalytic Reduction of CO2 to Liquid Products in Gas-Fed Electrolyzers
- NETL Site Support Contractor, National Energy Technology Laboratory
The room-temperature electrochemical reduction of carbon dioxide to liquid products is a soaring carbon utilization technology with an energy and environmental impact, offering a pathway to convert renewable energy into valuable C1 (e.g., formic acid) and C2+ products (e.g., ethanol and n-propanol)1. Gas-fed flow electrolyzers, in which a gas diffusion layer is used to transport gaseous CO2 into the electrode, have emerged as promising electrocatalytic reactors for large-scale applications, reaching competitive production costs for carbon monoxide (CO) and formic acid (HCOOH). Despite their increased use in recent years, several factors governing their performance have yet to be understood.
