摘要：

The p-type CaFe2O4 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 CaFe2O4 thin films exhibit high photoelectrochemical performances (-117 mu A/cm(2) at -03 vs. SCE) for the hydrogen generation reaction even without applying any external voltage.
