Dr Alexander Rudnev (University of Bern)04/11/2014, 12:00Electrocatalytic conversion of CO2 into gaseous and liquid fuels has a great potential. However, significant conceptual and technological advances are still needed to make this process economically viable. Most studies on CO2 electroreduction were carried out using aqueous electrolytes. The solubility of CO2 in water is rather low, which leads to an undesirably low rate of mass transfer to the...Go to contribution page

Mr Motiar Rahaman (PhD Student)04/11/2014, 12:00The efficient conversion of CO2 into hydrocarbon fuels has attracted great attention in recent years. Our present work relates to the optimization of Cu:Au catalyst for the electro-reduction of CO2 in aqueous media. We synthesized various compositions of CuAu alloy nano-particles on vulcan carbon support by means of a single-step boro-hydride reduction process. The structure, composition and...Go to contribution page

Dr Pekka Peljo (EPFL)04/11/2014, 12:00Redox flow batteries (RFBs) are very well suited for storing the intermittent excess supply of renewable electricity [1]. However, conventional RFBs cannot in many situations utilize all the available “junk” electricity due to a limited storage capacity, as they are charged and discharged electrochemically, with electricity stored as chemical energy in the electrolytes. In the RFB system...Go to contribution page
