In Situ Investigation of the Interface of Photoanodes and
Electrocatalysts in Photoelectrochemical Water Oxidation Using Dual Working
Electrode Photoelectrochemistry
Here, we demonstrate the in situ growth of ultrathin FeFx nanolayers on Fe2O3 photoanodes, acting as a highly efficient cocatalyst to accelerate hole transfer for improving PEC activity.
The unprecedented FeP/Ti–Fe2O3 possesses the advantages of efficient charge transfer in the bulk photoanode and at the interface of the photoanode and the electrolyte.
Cascade charge transfer between graphene quantum dots and Ag nanocrystals in photoelectrochemical water splitting was finely regulated by layer-by-layer (LbL) assembly.
α-Fe2O3@Co3O4 core–shell wormlike nanoarrays were fabricated via in situ growth of Co3O4 on wormlike α-Fe2O3, showing superior photoelectrochemical water oxidation performance.
