KOH-activated multi-walled carbon nanotubes as platinum supports for oxygen reduction reaction

He, C.; Song, S.; Liu, J.; Maragou, V.; Tsiakaras, P. (2010)

In the present investigation, multi-walled carbon nanotubes (MWCNTs) thermally treated by KOH were adopted as the platinum supporting material for the oxygen reduction reaction electrocatalysts. FTIR and Raman spectra were ...

Liolios, C.; Doukas, C.; Fourlas, G.; Maglogiannis, I. (2010)

The use of sensor networks for healthcare, well-being, and work-ing in extreme environments has long roots in the engineering sector in medicine and biology community. With the growing needs in ubiquitous communications ...

Understanding the electrocatalytic activity of PtxSny in direct ethanol fuel cells

Wang, Y.; Song, S.; Andreadis, G.; Liu, H.; Tsiakaras, P. (2011)

In the present work, the activity of PtxSny/C catalysts towards ethanol, acetaldehyde and acetic acid electrooxidation reactions is investigated for each one separately by means of cyclic voltammetry. To this purpose, a ...
