EPFL/Technion team develops “champion” nanostructures for efficient solar water-splitting to produce hydrogen

Green Car Congress

-Fe 2 O 3 (hematite) electrodes that achieve the highest photocurrent of any metal oxide photoanode for photoelectrochemical water-splitting under 100?mW?cm The whole point of our approach is to use an exceptionally abundant, stable and cheap material: rust.
