Friday Oct. 7th 12:00 - 12:30 - Anna Dobrzeniecka Synthesis and characterisation of ethanol tolerant electrocatalyst for oxygen reduction There is a need to produce a new selective ethanol-tolerant catalysts for the oxygen reduction reaction that would operate effectively in ethanol fuel cells. The latter systems have been recently considered as alternatives to hydrogen driven fuel cell. Our first choice of compounds includes the carbon supported derivatives of Fe and Co macrocycles i.e. the systems that are known to exhibit some reactivity towards oxygen reduction. Different parameters, like geometric area of carbon support, choice of a metal, details of a pyrolysis step have been investigated to get, at the end, the efficient Co/Fe nitrogen doped carbon supported catalyst. In spite of low cost of material production, the relatively low mass-specific activity and stability of the proposed systems still limit their application. Therefore, we have also explored RuSe catalysts, that are very attractive due to their high activity and ethanol tolerance, and we propose easy synthetic approach leading to fabrication of new, highly-efficient RuSe catalyst for oxygen reduction.
