MIT's Artificial Leaf Uses Sunlight To Split Water Into Oxygen & Hydrogen

MIT is always innovating and finding solutions for the biggest problems mankind may face in future. Researchers at MIT have developed an Artificial Leaf that can split water into Oxygen and Hydrogen in presence of sunlight, without needing wires or electricity. With this technological advancement, MIT researchers have been able to create an artificial leaf. This artificial leaf is actually a silicon solar cell with two different materials on either side. Once immersed in water and exposed to the sunlight, the leaf begins producing bubbles on either side of the surface. The video shows formation of Oxygen and Hydrogen bubbles on either side of this artificial leaf. We already have mechanisms to collect Oxygen and Hydrogen produced by artificial leafs separately and then store them or use them for Electricity generation.

Nocera, the Henry Dreyfus Professor of Energy and professor of chemistry at MIT explains that this artificial leaf has been produced using material that's available in abundance. It uses cobalt, silicon and nickel and works in regular water. The development of Artificial Leaf opens many new avenues of investigation and development of reliable and cheaper sources of energy which will last for hundreds of years. Further information on the project is available on below mentioned link. Check out this short video that shows the artificial leaf in action -
