Researchers Produce Liquefiable Fuels Through Artificial Photosynthesis

Researchers of University of Illinois could produce fuels using water, carbon dioxide and visible light through artificial photosynthesis.

According to the new research, researchers developed an artificial process that uses the same green light portion of the visible light spectrum used by plants during natural photosynthesis to convert CO2 and water into fuel, in conjunction with electron-rich gold nanoparticles that serve as a catalyst. The new findings are published in the journal Nature Communications.

"The goal here is to produce complex, liquefiable hydrocarbons from excess CO2 and other sustainable resources such as sunlight," said Prashant Jain, a chemistry professor and co-author of the study. "Liquid fuels are ideal because they are easier, safer and more economical to transport than gas and, because they are made from long-chain molecules, contain more bonds—meaning they pack energy more densely."

Gold nanoparticles work particularly well as a catalyst, Jain said, because their surfaces interact favorably with the CO2 molecules, are efficient at absorbing light and do not break down or degrade like other metals that can tarnish easily.

As exciting as the development of this CO2-to-liquid fuel may be for green energy technology, the researchers acknowledge that Jain's artificial photosynthesis process is nowhere near as efficient as it is in plants.

"We need to learn how to tune the catalyst to increase the efficiency of the chemical reactions," he said. "Then we can start the hard work of determining how to go about scaling up the process. And, like any unconventional energy technology, there will be many economic feasibility questions to be answered, as well."
