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.

该项目将致力于低成本电催化剂的基础研究和开发，用于有效和直接氧化还原的微生物代谢产物，用于微生物燃料电池的发电。目的是开发一种完全不含贵金属的微生物燃料电池，其性能大大超过目前的微生物燃料电池。这项工作的基础将是第一次彻底和系统地研究碳化钨基催化剂的电催化作用（i）对微生物代谢物的氧化，（ii）在微生物燃料电池条件下（中性pH值，环境温度）和（iii）作为电催化剂的结构，物理和化学性质的函数。基于此调查和电催化和生物催化的相互作用的研究，定制的电催化剂应开发结合高电流密度和库仑产率，在高生物相容性和稳定性。
