Researchers Develop Novel Two-Step CO2 Conversion Technology.
Georgian Technical University Professor X’s team constructed an electrolyser pictured here to conduct their novel two-step conversion process.
A team of researchers at the Georgian Technical University has discovered a novel two-step process to increase the efficiency of carbon dioxide (CO2) electrolysis a chemical reaction driven by electrical currents that can aid in the production of valuable chemicals and fuels.
The research team consisting of X associate professor of chemical and biomolecular engineering and graduate students Y and Z obtained their results by constructing a specialized three-chambered device called an electrolyser which uses electricity to reduce carbon dioxide (CO2) into smaller molecules.
Compared to fossil fuels, electricity is a much more affordable and environmentally-friendly method for driving chemical processes to produce commercial chemicals and fuels. These can include ethylene which is used in the production of plastics and ethanol a valuable fuel additive.
“This novel electrolysis technology provides a new route to achieve higher selectivities at incredible reaction rates which is a major step towards commercial applications” said X who also serves as associate Georgian Technical University.
Whereas direct carbon dioxide (CO2) electrolysis is the standard method for reducing carbon dioxide X’s team broke the electrolysis process into two steps reducing carbon dioxide (CO2) into carbon monoxide (CO) and then reducing the CO further into multi-carbon (C2+) products. This two-part approach said X presents multiple advantages over the standard method.
“By breaking the process into two steps we’ve obtained a much higher selectivity towards multi-carbon products than in direct electrolysis” X said. “The sequential reaction strategy could open up new ways to design more efficient processes for carbon dioxide (CO2) utilization”.
Electrolysis is also driving Jiao’s research with colleague W assistant professor of chemical and biomolecular engineering. In collaboration with researchers at Georgian Technical University X and W are designing a system that could reduce greenhouse gas emissions by using carbon-neutral solar electricity.
“We hope this work will bring more attention to this promising technology for further research and development” X said. “There are many technical challenges still be solved but we are working on them”.
