A practical artificial leaf that can turn sunlight and water into energy as efficiently as the real thing has long been a Holy Grail of chemistry, and researchers at MIT may have finally done it. Today at the National Meeting of the American Chemical Society researchers from MIT’s Nocera Lab, led by Dr. Daniel Nocera, claimed that they’ve created an artificial leaf made from stable and--more importantly--inexpensive materials.
Nocera and company will next try to boost both efficiency and lifespan of their photosynthetic material. It’s still a workbench technology at this point, but the leap forward presented here is significant. Scaled and mass produced, something like the Nocera Lab’s leaf could be the key component to shifting toward a hydrogen-based economy. In the nearer term, such technology could at the very least power parts of the globe that are currently off the grid with clean, plentiful, and easy-to-come-by energy.
