Could future gasoline come from thin air and sunlight instead of oil wells? A team of Chinese scientists has unveiled a lab system that imitates plant photosynthesis to turn carbon dioxide and water into gasoline building blocks using only sunlight. Their work hints at a way to recycle a major greenhouse gas while still using existing engines and fuel infrastructure.
In an artificial photosynthesis study, the researchers report a “charge reservoir” material that stores solar energy as electrical charge, then delivers it on demand to drive reactions. The system converts carbon dioxide into carbon monoxide, a key building block for synthetic fuels, and uses water as its only electron source instead of extra helper chemicals.
Although still a lab device, the setup works under natural sunlight and is meant to connect renewable energy to industry and transport.
