This project will be dedicated to the fundamental investigation and development of low-cost electrocatalysts for an efficient and direct oxidation of reduced microbial metabolites for electricity generation in microbial fuel cells. It is the aim to develop a fully noble metal free microbial fuel cell that considerably exceeds the performance of present microbial fuel cell. Fundament of this endeavour will be the first thorough and systematic investigation of the electrocatalysis at tungsten carbide based catalysts (i) towards the oxidation of microbial metabolites, (ii) under microbial fuel cell conditions (neutral pH, ambient temperature) and (iii) as a function of the structural, physical and chemical properties of the electrocatalyst. Based on this investigation and the study of the interaction of electrocatalysis and biocatalysis a tailored electrocatalyst shall be developed that combines high current densities and coulombic yields, at high biocompatibility and stability.
