In article 1500358, D. Fattakhova‐Rohlfing, T. Bein and co‐workers describe the preparation of ultrasmall dispersible Co 3 O 4 nanocrystals and successfully apply them as a surface treatment to nanostructured hematite photoanodes in light‐driven water splitting. The treatment with nanoparticles leads to a striking photocurrent increase, which is attributed to a suppression of surface electron‐hole recombination processes on millisecond to second time scales. The cover image is designed by Christoph Hohmann, Nanosystems Initiative Munich (NIM).
