Patterning alternate TiO2 and Cu2O strips on a conductive substrate as film photocatalyst for Z-scheme photocatalytic water splitting
文献摘要：
Semiconductor heterostructures mediated by electrical conductors are very promising for Z-scheme pho-tocatalytic water splitting.In contrast to conventional particulate heterostructures,alternate TiO2 and Cu2O film stripes patterned parallel on a fluorine-doped tin oxide(FTO)conductive substrate was fabri-cated as a model film photocatalyst to study the characteristics of the photogenerated charge transfer process.The Z-scheme transfer process with an effective transport distance of up to 5 μm occurs only in regions distant from the TiO2/Cu2O strip edges through the FTO substrate from the bottom.In contrast,the transfer of charge around their contact regions follows the conventional transfer process through the TiO2/Cu2O strip interface.These results indicate that the Z-scheme transfer process occurring in such a large region dominates the charge transfer processes in the TiO2/FTO/Cu2O pattern film heterostructure.Importantly,unlike the single component film,which is inactive for photocatalytic overall water splitting,the modified TiO2/Cu2O pattern film can induce photocatalytic overall water splitting at a stoichiometric H2/O2 ratio close to 2∶1.These findings have significant implications in designing efficient heterostruc-tures by employing a Z-scheme charge transfer process.
