Photoactive in one step! A nanocomposite water-oxidation photocatalyst was assembled by a straightforward and one-step spin-coating procedure of a Ti- and Ni-containing molecule on nanostructured WO3. The photoanode oxidizes water to O2 with good activity and stability in alkaline solution, and thereby features light absorption, charge separation and water-oxidation catalysis (see scheme).

Pyridyl iodides were synthesized to serve as effective, economical, green and dual function additives for high efficiency and stable DSCs. Using commercial P25 as the photoanode, a high PCE of 7.81% was achieved with a pyridyl iodide-containing electrolyte. Meanwhile, DSCs based on our novel electrolytes demonstrated better stability.

Deployment of solar fuels technology requires photoanodes with long term stability, which can be accomplished using light absorbers that self-passivate under operational conditions. Several copper vanadates have been recently reported as promising photoanode materials, and their stability and self-passivation is demonstrated through a combination of Pourbaix calculations and combinatorial exper...
