Nanocrystals and Nickel Catalyst Improve Light-Based Hydrogen Production

Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse gas emissions. A group of chemists at the University of Rochester is adding to its appeal by increasing the output and lowering the cost of current light-driven hydrogen-production systems. One disadvantage of current methods of hydrogen production has been the lack of durability in the light-absorbing material, but the Rochester scientists were able to overcome that problem by incorporating nanocrystals.
