Faraday Discussion 155: Artificial Photosynthesis

In artificial photosynthesis, sunlight absorbed by an electron donor (D) causes an electron to transfer to a nearby electron acceptor (A); a reaction that does not occur in the dark. Several concerted electron-transfer reactions are needed to effect water splitting and intermediary electrons and positive holes have to be stored for a few seconds or so at a redox catalyst. Here, we focus on the discussion relating to the use of pgms either as specific catalysts or as photon collectors. Full article
