Summary
The societal transformation to renewable energy necessitates more efficient ways to store energy. This can be achieved by direct energy storage in batteries or supercapacitors (SCs) or by using electrocatalysis to convert energy, e.g., to green hydrogen. The efficiency of such processes can be enhanced, by increasing the surface of the electrode. Increase of the surface can be achieved by introducing pores into the electrodes. However, in recent years the porosity has reached the nanometre scale. At this scale the pores become so small that the interfacial layer known as double-layer, as well as ions at the surface, are confined.
In NanoC3, we aim to understand the effect of confinement of ions and of the double-layer on charge storage and hydrogen production. For this purpose, we will analyze materials, with unprecedented control of the pore size, provided from collaborations with material scientists, using innovative surface science techniques. These measurements are enabled by the expertise of the ER in microcalorimetry and of the host institution in spectroscopy and electrocatalysis.
To study confinement of the double-layer, gold electrodes with tuneable slits will be provided by Serge Lemay (Twente, NL). Gold is a well-studied model electrode to investigate the double-layer and hydrogen evolution, allowing for comparison of the results with literature data. Theoretical calculations will be performed by Alexei Kornyshev (Imperial College, UK).
To obtain the even smaller pore sizes necessary to study ion confinement, MoS2 and V2O5 electrodes will be provided by S. Fleischmann (KIT, GER). These layered materials can be tuned by intercalating molecular pillars, leading to an increase of the interlayer spacing. MoS2 can be used to substitute the expensive Pt in the hydrogen evolution, while V2O5 is a well-researched SC, exhibiting ion confinement.
In summary, the goal of NanoC3 is to advance the field of electrocatalysis in a new and yet unexplored direction.
