Carbon materials – highly porous, partially graphitic, and hetero-doped – are rising electrodes in electrochemical devices for energy storage. This is a curious twist of history: for many millennia carbon was mostly a low-value energy source, only good for burning up. These days, we find carbon electrodes in power sources as diverse as batteries, fuel cells and supercapacitors. The microstructure of such carbons – affecting much of their electrochemical function – is hard to design and control. We have recently reported a family of N-doped, hierarchically porous carbons, whose structure and composition can be tuned rationally, opening the way to in-depth studies of structure–activity links. These carbons are derived from metal-organic frameworks (MOFs), whose composition can be controlled and correlated to the final carbon structure, and ultimately, electrocatalytic properties. This talk will discuss design principles of carbon-based electrocatalysts, focusing on elegance of synthesis, separation of structural variables, and understanding electrocatalytic function.

Bio: David Eisenberg received his BSc, MSc, and PhD in Chemistry at the Hebrew University of Jerusalem, Israel (2002-2011, with Prof. Roy Shenhar). His thesis focused on diffusion NMR of self-assembled buckyball fragments. In parallel, he worked in an Israeli national lab developing transparent oxide ceramics, taught chemistry in an international high-school in kibbutz Tzuba, and operated a small business building websites for academics.
After graduation, David Eisenberg travelled to the University of Texas at Austin (USA) as a Fulbright / Ilan-Ramon Fellow to pursue post-doctoral research in electrochemistry (with Prof. Allen J. Bard and Prof. Adam Heller). He then moved to the University of Amsterdam in the Netherlands to lead an electrocatalysis team at the Heterogeneous Catalysis and Sustainable Chemistry group of Prof. Gadi Rothenberg.
On February 2017, David Eisenberg joined the Schulich Faculty of Chemistry at the Technion – Israeli Institute of Technology. His group (www.david-eisenberg.com) focuses on the materials science of fuel cell electrocatalysts, with a special interest in 3D carbons with designed microstructure and doping.
