‘Artificial leaf’ converts CO2 into biofuel, potential new strategy in battle to slow climate change

| November 6, 2019

Scientists have created an “artificial leaf” to fight climate change by inexpensively converting harmful carbon dioxide (CO2) into a useful alternative fuel. The new technology was inspired by the way plants use energy from sunlight to turn carbon dioxide into food.

“We call it an artificial leaf because it mimics real leaves and the process of photosynthesis,” said Yimin Wu, an engineering professor at the University of Waterloo who led the research. “A leaf produces glucose and oxygen. We produce methanol and oxygen.”

The key to the process is a cheap, optimized red powder called cuprous oxide …. The powder then serves as the catalyst, or trigger, for another chemical reaction when it is mixed with water into which carbon dioxide is blown and a beam of white light is directed with a solar simulator.
