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 ...

Two-step sequence for synthesis of efficient PtSn@Rh/C catalyst for oxidizing ethanol and intermediate products

Song, S.; He, C.; Liu, J.; Wang, Y.; Brouzgou, A.; Tsiakaras, P. (2012)

PtSn@Rh/C-HT catalysts were designed and synthesized by a two-step sequence synthesis: Rh was firstly deposited on the carbon support and then PtSn through microwave assisted polyol method, followed by the heat treatment ...

Efficient and poison-tolerant PdxAuy/C binary electrocatalysts for glucose electrooxidation in alkaline medium
