Developed by scientists from the University of Cambridge, a new device can convert carbon dioxide, water, and sunlight into clean fuels. This wireless device-based on an advanced ‘photosheet’ technology- is a significant step toward achieving artificial photosynthesis.
Despite being a promising way to reduce carbon emissions, this new device could be scaled up and used on energy ‘farms’ similar to solar farms.
Achieving artificial photosynthesis with a high degree of selectivity is quite difficult. Thus, converting as much of the sunlight as possible into the fuel you want is better rather than be left with a lot of waste.
Professor Erwin Reisner, the paper’s senior author said, “In addition, storage of gaseous fuels and separation of by-products can be complicated – we want to get to the point where we can cleanly produce a liquid fuel that can also be easily stored and transported.”
The device do not require additional components or electricity. It solely relies on photocatalysts embedded on a sheet to produce a so-called photocatalyst sheet. The sheets are made up of semiconductor powders, which can be prepared in large quantities easily and cost-effectively.
