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, outlined in a paper published today in the journal Nature Energy, 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."
