Abstract

There is a growing interest in developing dye‐sensitized photocatalytic systems (DSPs) to produce molecular hydrogen (H 2 ) as alternative energy source. To improve the sustainability of this technology, we replaced the sacrificial electron donor (SED), typically an expensive and polluting chemical, with an alcohol oxidation catalyst. This study demonstrates the first

dye‐sensitized system using a diketopyrrolopyrrole dye covalently linked to 2,2,6,6‐tetramethyl‐1‐piperidine‐ N ‐oxyl (TEMPO) based catalyst for simultaneous H 2 evolution and alcohol‐to‐aldehyde transformation operating in water with visible irradiation.
