MIT Research Team Develops ‘Artificial Leaf’ that Splits Water, Produces Hydrogen & Oxygen Gas

A research team led by pioneering clean energy technology developer and MIT professor Daniel Nocera has developed an ‘artificial leaf’ that like its namesake captures energy from sunlight and produces electricity that it then turns into chemical fuel — hydrogen and oxygen gas. Made up of a thin sheet of silicon solar cell material bonded either side with thin sheets of catalytic cobalt and nickel-molybdenum-zinc, when placed in an ordinary container of water, the ‘artificial leaf’s’ solar photovoltaic (PV) cells generate an electric current which catalysts bonded to the solar cell sheet use to produce oxygen and hydrogen gas. Collected, stored and coupled to hydrogen fuel cells, the gases could be used as an energy carrier that would create electricity on demand at scales ranging from individual home use on up to utility-scale power plants. “I think there’s going to be rea...
