Artifical Leaf Produces Syngas without CO2

Artifical Leaf Produces Syngas without CO2
Oct-24-19
An artificial leaf able to produce synthetic gas without releasing carbon dioxide could be used to create sustainable liquid fuel alternatives.

The artificial leaf developed by a team from the University of Cambridge will produce syngas, which is used to create a number of different products such as fuels and plastics. While syngas is a common and useful product, its production releases carbon dioxide into the air. To reduce those emissions, the team from Cambridge created an artificial leaf prototype with two light absorbers—one that produces oxygen and one that carries out the chemical reaction that forms the syngas mixture. The light absorbers will function even on cloudy or rainy days, making the technology more useful in a variety of climates.

According to senior author Eriwn Reisner, “What we’d like to do next, instead of first making syngas and then converting it into liquid fuel, is to make the liquid fuel in one step from carbon dioxide and water.”
