Nanoparticle Opens the Door to Clean-Energy Alternatives (2 of 2) (image) Penn State Share Print E-Mail Caption Cheaper clean-energy technologies could be made possible thanks to a new discovery. Research team members led by Raymond Schaak, a professor of chemistry at Penn State University, have found that an important chemical reaction that generates hydrogen from water is effectively triggered -- or catalyzed -- by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abundant on Earth. This illustration shows hydrogen gas bubbling off of the surface of a nickel phosphide crystal.
