Catalytic gold nanoclusters promise rich chemical yields
(Phys.org) —Old thinking was that gold, while good for jewelry, was not of much use for chemists because it is relatively nonreactive. That changed a decade ago when scientists hit a rich vein of discoveries revealing that this noble metal, when structured into nanometer-sized particles, can speed up chemical reactions important in mitigating environmental pollutants and producing hard-to-make specialty chemicals. Catalytic gold nanoparticles have since spurred hundreds of scientific journal articles. With the world catalyst market poised to hit $19.5 billion by 2016, gold nanoparticles may find commercial as well as intellectual importance, as they could ultimately lead to novel catalysts for energy, pharmacology and diverse consumer products.
