Synthetic photosynthesis could lead to greener energy

A team of chemists from the Brookhaven National Laboratory and Virginia Tech in the US, have taken a step forward in using synthetic photosynthesis to produce clean energy, according to a study published in the Journal of the American Chemical Society. The researchers built two supramolecules  substances that are assembled from a number of molecular subunits or components — made from light-harvesting ruthenium ions attached to a central catalyst of rhodium ions. Photosynthesis is one of nature's most efficient processes, producing oxygen as well the nutrients and energy required for plants to grow. Replicating photosynthesis will allow scientists to not only produce clean energy, but also to remove carbon dioxide from the air.
