Solar fuels soon? Researchers succeed in making ethylene from CO2
Researchers at the University of Michigan have developed an artificial photosynthesis system that converts carbon dioxide into ethylene.
The resulting product is ethylene (chemical formula – C 2 H 4), and this method has demonstrated a remarkable ability to produce it efficiently, abundantly, and consistently compared to other artificial photosynthesis systems currently in use. The system developed by the University of Michigan researchers absorbs light through two kinds of semiconductors: a forest of gallium nitride nanowires, each just 50 nanometers (a few hundred atoms) wide, and the silicon base on which they were grown. “In the future, we want to produce some other multicarbon compounds such as propanol with three carbons or liquid products,” said Bingxing Zhang, U-M assistant research scientist in electrical and computer engineering and first author of the paper.
