Efficient excited-state electron transfer between an iron(III) photosensitizer and organic electron donors was realized with green light irradiation.
A model is proposed wherein ET in annealed SnO2|TiO2 is rate-limited by electron transport in the shell, while ET in unannealed SnO2|TiO2 is rate-limited by electron escape from the core. The model is consistent with a comparative study of ZrO2|TiO2 materials for which insulating ZrO2 cores are energetically inaccessible to electrons. These mechanistic insights provide guidance on how to manipulate core|shell nanostructures for applications in solar water splitting.
