A great leap forward has been made by researchers at Florida State University – efficient artificial photosynthesis. In their article published recently in The Journal of Physical Chemistry Kevin P Lucht and Jose L.Medoza-Cortes describe a process of artificial photosynthesis using a layer of manganese oxide (also known as birnessite). The birnessite breaks down water (H2o) into hydrogen (H) and oxygen (O2).
Oxygen is of course important for our survival but hydrogen too is useful, as a source of energy. There are already a handful of cars running on hydrogen fuel cells, Hyundi and Toyota have recently announced their intention to bring cars running on this technology to the mass market in 2016 and the fuel cells can be used to power anything electrical.
The process will enable hydrogen energy to be gleaned from rainwater with only a single layer of material, the process is much more efficient than any similar ideas developed previously. It’s a carbon neutral system so could go a long way to help reduce our emissions, “Perhaps in the future, you could put this material on your roof and it could turn rain water into energy with the help of the sun.” (Mendozo-Cortes).
