A novel nanoparticulate platinum catalyst outperforms commercial platinum catalysts in terms of stability, oxidation activity, and resistance to carbon monoxide poisoning, according to chemists at Cornell University (J. Am. Chem. Soc., DOI: 10.1021/ja102931d). The study could lead to longer lasting and better performing catalysts for proton-exchange-membrane fuel cells, which in turn could hasten widespread deployment of these electrochemical power generators in transportation . . .
