Electrochemical Conversion Of CO2
The electrochemical conversion of CO2 has switched from a lab curiosity to a commercially viable process. Lab-scale electrolyzers are already being sold and Pilot units are moving toward commercialization. The growth of the field is being driven by falling price of renewable energy, the need to decarbonize the economy and the fact that the processes are starting to become commercially relevant.
Researchers from Dioxide Materials and the University of British Columbia provide an excellent review of commercially relevant low-tempertature electrochemical conversion of CO2 to useful products. The article was recently published in Nature Nanotechnology and includes major advances in the field from 2018 to 2020 such as:
- Pilot scale development of CO2 to CO electrolyzers
- Direct Formic acid generation of CO2
- Production of C2 products
- Two-step electrolysis
- Supported organometallic, metal–organic framework (MOF) and single-atom catalysts
- Role of Ligands to direct surface reactions in improving selectivity
In most cases, Faradaic efficiencies of 80% or more and current densities above 200 mA cm−2 can be reproducibly achieved. This is due to key advances in nanocatalysts and reactor design highlighted in the article.
