Title: Semi-synthetic strategy

Abstract

Semi-artificial photosynthesis offers advantages over purely natural or synthetic routes to producing chemicals from solar energy, but devices based on it have remained elusive. Now, researchers couple a dye-sensitized photoanode with natural components to generate H2 photoelectrochemically from water without additional bias.

Fig. 1 Fig. 1: Semi-artificial photosynthetic device for solar-driven hydrogen production. a, Photosystem II (PSII) is composed of the reaction centre and oxygen-evolving complex and light-absorbing antenna protein complex. PSII is wired to a light-absorbing dye by a conducting polymer. Photon absorption by the PSII antenna complex drives the water oxidation reaction,more » and the resulting electrons (e) transfer through the conducting polymer to be re-energized by the dye, which has a complementary absorption spectrum to PSII. Energized electrons are transferred to a second electrode where the hydrogenase (brown spheres, with the catalytic site represented in orange) catalyses the production of H2. b, The combined light absorption by PSII and the dye captures a much wider range of the solar spectrum than would PSII alone, as shown in the solution’s UV–visible spectrum. Panel b is adapted with permission from ref. 3, Nature Publishing Group.« less
