The results are reported in the journal Syngas is currently made from a mixture of hydrogen and carbon monoxide, and is used to produce a range of commodities, such as fuels, pharmaceuticals, plastics and fertilisers.
Your opinions are important to us. The researchers also used cobalt as their molecular catalyst, instead of platinum or silver. ScienceDaily.
About the artificial leaf The device is inspired by photosynthesis -- the natural process by which plants use the energy from sunlight to turn carbon dioxide into food. We do not guarantee individual replies due to extremely high volume of correspondence. The Cambridge researchers say the reason they have been able to make theirs produce syngas sustainably is thanks the combination of materials and catalysts they used.These include state-of-the-art perovskite light absorbers, which provide a high photovoltage and electrical current to power the chemical reaction by which carbon dioxide is reduced to carbon monoxide, in comparison to light absorbers made from silicon or dye-sensitised materials.
"The research was carried out in the Christian Doppler Laboratory for Sustainable SynGas Chemistry in the University's Department of Chemistry. Rather than running on fossil fuels, the artificial leaf is powered by sunlight, although it still works efficiently on cloudy and overcast days.

The team's fundamental research to produce syngas as the basis for liquid fuel in a carbon neutral way is ground-breaking," said Michael-Dieter Ulbrich, Senior Advisor at OMV.Other 'artificial leaf' devices have also been developed, but these usually only produce hydrogen. It was co-funded by the Austrian government and the Austrian petrochemical company OMV, which is looking for ways to make its business more sustainable. ScienceDaily, 21 October 2019.

At the other end you get hydrogen and carbon monoxide, which can then make syngas. The results are reported in the journal Nature Materials. Rather than running on fossil fuels, the artificial leaf is powered by sunlight, although it still works efficiently on cloudy and overcast days. "This means you are not limited to using this technology just in warm countries, or only operating the process during the summer months," said Ph.D. student Virgil Andrei, first author of the paper.

Being able to produce it sustainably would be a critical step in closing the The device Reisner and his colleagues produced is inspired by photosynthesis—the natural process by which plants use the energy from sunlight to turn carbon dioxide into food.On the artificial leaf, two light absorbers, similar to the molecules in plants that harvest sunlight, are combined with a catalyst made from the naturally abundant element cobalt.When the device is immersed in water, one light absorber uses the catalyst to produce oxygen. Have any problems using the site?
by A widely-used gas that is currently produced from fossil fuels can instead be made by an 'artificial leaf' that uses only sunlight, carbon dioxide and water, and which could eventually be used to develop a sustainable liquid fuel alternative to petrol.
Questions?University of Cambridge. The results are reported in Nature Materials. "OMV has been an avid supporter of the Christian Doppler Laboratory for the past seven years. But we are confident that we are going in the right direction, and that we have the right catalysts, so we believe we will be able to produce a device that can demonstrate this process in the near future.

"There is a major demand for liquid fuels to power heavy transport, shipping and aviation sustainably," he said.
