文摘
- •
In PSII metal oxide hybrid systems, direct electron transfer occurs from QA to the electrode surface.
- •
Electron transfer through the nanostructured TiO2 is rate-limiting.
- •
Redox mediators can overcome the limitation by taking electrons from the TiO2 semiconductor to the electrode surface.
