Abstract
The p-type CaFe 2O 4 nanofilms with a thickness of about 100 nm on F doped tin-oxide-coated (FTO) glass sheets were fabricated by a pulsed laser deposition (PLD) method at a relatively low temperature. Furthermore, their photoelectrochemical properties for splitting water into hydrogen have also been studied in detail. It has been found that these CaFe 2O 4 thin films exhibit high photoelectrochemical performances (−117 μA/cm 2 at −0.3 vs. SCE) for the hydrogen generation reaction even without applying any external voltage.
