Zhou, W. J.; Song, S. Q.; Li, W. Z.; Zhou, Z. H.; Sun, G. Q.; Xin, Q.; Douvartzides, S.; Tsiakaras, P. (2005)

In the present work, several carbon supported PtSn catalysts with different Pt/Sn atomic ratios were synthesized and characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM) and X-ray photoelectron ...

Pt-based anode catalysts for direct ethanol fuel cells

Zhou, W. J.; Song, S. Q.; Li, W. Z.; Sun, G. Q.; Xin, Q.; Kontou, S.; Poulianitis, K.; Tsiakaras, P. (2004)

In the present work, several carbon supported PtSn and PtSnRu catalysts were prepared with different atomic ratios and tested in direct ethanol fuel cells (DEFC) operated at lower temperature (T=90 degreesC). XRD and TEM ...

Direct ethanol PEM fuel cells: The case of platinum based anodes

Song, S. Q.; Zhou, W. J.; Zhou, Z. H.; Jiang, L. H.; Sun, G. Q.; Xin, Q.; Leontidis, V.; Kontou, S.; Tsiakaras, P. (2005)

PtSn/C catalysts were prepared by the direct decoration of Pt/C with Sn through a modified poly process. XRD results showed there existed obvious SnO2 in this catalyst, different from the PtSn/C prepared by co-precipitation, ...
