    • Bi- and tri-metallic Pt-based anode catalysts for direct ethanol fuel cells 

      Zhou, W. J.; Li, W. Z.; Song, S. Q.; Zhou, Z. H.; Jiang, L. H.; Sun, G. Q.; Xin, Q.; Poulianitis, K.; Kontou, S.; Tsiakaras, P. (2004)
      In the present work, several Pt-based anode catalysts supported on activated carbon XC-72R were prepared by using a novel method, characterized and tested. XRD analysis and TEM images indicated that all of anode catalysts ...

    • Direct ethanol fuel cells based on PtSn anodes: The effect of Sn content on the fuel cell performance 

      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.; Zhou, Z.; Song, S.; Li, W.; Sun, G.; Tsiakaras, P.; Xin, Q. (2003)
      In the present work several Pt-based anode catalysts supported on carbon XC-72R were prepared with a novel method and characterized by means of XRD, TEM and XPS analysis. It was found that all these catalysts are consisted ...

    • 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 ...
