Identification of catalytic sites for oxygen reduction in iron- and nitrogen-doped graphene materials.

Nature materials

Zitolo A, Goellner V, Armel V, Sougrati MT, Mineva T, Stievano L, Fonda E, Jaouen F.
PMID: 26259106
Nat Mater. 2015 Sep;14(9):937-42. doi: 10.1038/nmat4367. Epub 2015 Aug 10.

While platinum has hitherto been the element of choice for catalysing oxygen electroreduction in acidic polymer fuel cells, tremendous progress has been reported for pyrolysed Fe-N-C materials. However, the structure of their active sites has remained elusive, delaying further...

Reactivity of site-isolated metal clusters: propylidyne on gamma-Al2O3-supported Ir4.

Journal of the American Chemical Society

Argo AM, Goellner JF, Phillips BL, Panjabi GA, Gates BC.
PMID: 11456875
J Am Chem Soc. 2001 Mar 14;123(10):2275-83. doi: 10.1021/ja002818q.

To contrast the reactivity of supported metal clusters with that of extended metal surfaces, we investigated the reactions of tetrairidium clusters supported on porous gamma-Al2O3 (Ir4/gamma-Al2O3) with propene and with H2. Infrared, 13C NMR, and extended X-ray absorption fine-structure...

Fine-needle aspiration biopsy: use in diagnosis and management of pediatric thyroid diseases.
