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.”
Making methanol from carbon dioxide, the primary contributor to global warming, would both reduce greenhouse gas emissions and provide a substitute for the fossil fuels that create them.
The key to the process is a cheap, optimized red powder called cuprous oxide.
