Nanocrystal Catalyst Transforms Impure Hydrogen Into Electricity
Sep. 18, 2013 — The quest to harness hydrogen as the clean-burning fuel of the future demands the perfect catalysts -- nanoscale machines that enhance chemical reactions. Scientists must tweak atomic structures to achieve an optimum balance of reactivity, durability, and industrial-scale synthesis. In an emerging catalysis frontier, scientists also seek nanoparticles tolerant to carbon monoxide, a poisoning impurity in hydrogen derived from natural gas. This impure fuel -- 40 percent less expensive than the pure hydrogen produced from water -- remains largely untapped.
