Nanotubes reveal role of support in gold catalyst mystery
This was no ordinary hidden treasure. It involved nanotubes of gold rather than pots and was more or less hidden in plain site. But oddly enough, for reasons that researchers debated for years, tiny bits of the precious metal in careful arrangements would display hidden value, or extra power. The gold, in this case, is used as a catalyst to clean carbon monoxide (CO) from hydrogen fuel.
