Single-atom gold catalysts may offer path to low-cost production of fuel and chemicals

Thursday, November 27, 2014 - 14:00 in Physics & Chemistry

New catalysts designed and investigated by Tufts University School of Engineering researchers and collaborators from other university and national laboratories have the potential to greatly reduce processing costs in future fuels, such as hydrogen. The catalysts are composed of a unique structure of single gold atoms bound by oxygen to several sodium or potassium atoms and supported on non-reactive silica materials. They demonstrate comparable activity and stability with catalysts comprising precious metal nanoparticles on rare- earth and other reducible oxide supports when used in producing highly purified hydrogen.
