The fabrication of a CuO/ZnO/TiO2 nanofiber photocathode has been reported.
We achieved a photocurrent density (PCD) of −4.1 mA/cm2 without a co-catalyst.
Electrospun nanofibers were electroplated with copper and then air-dried and annealed.
The cupric CuO nanofibers exhibited nanotextured surfaces.
These CuO nanofibers were coated with ZnO and TiO2 by atomic layer deposition.
