Scientists Find New Way to Produce Hydrogen (IMAGE)
Caption
The figure shows aluminum clusters reacting with water to produce hydrogen. The image on the bottom depicts a water molecule (one hydrogen atom (red ball) and two oxygen atoms (silver balls)) splitting on the surface of an aluminum cluster. The blue regions are Lewis-acid sites and the orange regions are Lewis-base sites. The upper-right image shows multiple water molecules binding to the active sites of an aluminum cluster. The upper-left image shows the release of hydrogen (two silver balls surrounded by orange halo).
