Supported mixed metal nanoparticles as electrocatalysts

Freitag, Januar 19th, 2007

- in low temperature fuel cells
Kwong-Yu Chan, Jie Ding, Jiawen Ren, Shaoan Cheng, Kwok Ying Tsang, J. Mater. Chem., 2004, (4),505-516 (DOI: 10.1039/b314224h)
Recent developments in syntheses and electrocatalytic properties of mixed metal nanoparticles are reviewed specifically for applications in fuel cells. The role of nanostructured supports for the nanoparticles, such as ordered mesoporous carbon is […]

HOPG corrosion accelerated by Pt particles

Freitag, Januar 19th, 2007

- an AFM study by Zyun Siroma et al
Electrochemistry Communications, Volume 7, Issue 11 , November 2005, Pages 1153-1156 (http://dx.doi.org/10.1016/j.elecom.2005.08.014)
Platinum nanoparticles were deposited on HOPG and its stability in HClO4 at a fixed potential was investigated. The formation of blisters was observed after it was kept at 1.0 V vs. RHE, especially at and around […]
