Highly Organized Porous Electrodes – HOPE

Submission summary

In the general context of miniaturization there is an urgent need for many electrochemical applications, ranging from sensors to energy storage and conversion devices, to use electrodes with a very high active surface area in order to keep the current or power output at a sufficiently high level acceptable for practical use. This can be achieved by using porous electrodes. In the present project we plan to elaborate original porous electrochemical interfaces with a high degree of organization at various levels, ranging from the molecular and supramolecular scale to the sub-micrometer and micrometer level. This concept of multiscale tailoring is at its very beginning and needs a thorough fundamental investigation and validation. The in depth characterisation of the physico-chemical behaviour of the obtained complex structures will give us the possibility to understand and subsequently to optimize their properties. This should allow us finally to study potential applications in different fields ranging from catalysis to biosensors and renewable energy conversion systems. - - As a consequence the project will be divided into three major work packages: - 1. Elaboration of highly organized electrode materials with a complex structure - Recently synthesis strategies developed in our group will be further optimized to obtain multicomponent porous electrodes - 2. Detailed characterisation of the obtained materials - The obtained porous electrodes show an unusual physico-chemical behaviour that will be characterized in detail before being able to test them for practical applications. - - 3. Application of the porous electrodes as support for electrocatalytic reactions, (bio)sensors and biofuel cells - We will test these new electrodes after modification of their internal surface with molecular layers of a bioelectrocatalytic chain as biosensors, as anodes and cathodes in miniaturized biofuel cells and as measuring and stimulating electrodes in neuroscience. - - The total outcome of this project will be a certain number of highly original electrode structures, a good understanding of their complex physico-chemical behaviour and the fundamentals for some very promising applications. At the moment the different partners of the project are working at the forefront of the three individual work packages compared to the international level, and therefore combining their know-how should lead to synergetic effects that will produce most likely top-notch results. - - ...
