JACS cover - light-driven water electrolysis

A new publication by Dina Fattakhova-Rohlfing (IEK-1) and colleagues from Ludwig-Maximilians-Universität München (Thomas Bein et al.) has appeared in "Journal of the American Chemical Society (JACS)".

The paper deals with light-driven water electrolysis to generate hydrogen from sustainable energy sources, and reports the first time investigation of covalent organic frameworks (COFs) as a new class of photoelectrodes. Highly oriented COF films absorb light in the visible range to generate photoexcited electrons that diffuse to the surface and are transferred to the electrolyte, resulting in proton reduction and hydrogen evolution. The observed photoelectrochemical activity of the 2D-COF films and their photocorrosion stability in water pave the way for a novel class of photoabsorber materials with versatile optical and electronic properties that are tunable through the selection of appropriate building blocks and their three-dimensional stacking.

A graphic art illustrating the paper is selected for the Supplementary cover of the journal.
