Photoelectrochemical reduction of N,N'-dimethyl-4,4'-bipyridinium in aqueous media at p-type silicon: sustained photogeneration of a species capable of evolving hydrogen
Abstract
We report here a new approach to the energetically uphill generation of H₂ from H₂O. There have been numerous recent claims concerning chemical systems for the photoinduced evolution of H₂ from aqueous media, but in many of the systems reported there are sacrificial reducing agents used which cloud the overall thermodynamics and preclude sustained evolution of H₂. However, these studies have resulted in several interesting procedures for manipulating charge-transfer kinetics such that generation of H₂ is possible by schemes such as that represented:...
