Artificial photosynthesis aims to reproduce the catalytic power of enzymes from the capture of sunlight to strip electrons and protons from water to reduce CO2 or uses light to activate O2 to perform oxidationchemistry in a selective way. I will discuss on our recent results in these research thrusts
i) Organic semiconductors for the water splitting reaction
ii) CO2 to CO transformation with iron porphyrins catalysts
While often trapping intermediates following chemical and electrochemical pathways are
tedious, using a photoredox module to interrogate the light driven activation processes can
be alternative and elegant route.
