Realizing super-long Cu2O nanowires arrays for high-efficient water splitting applications with a convenient approach
Figures & Tables(5)
Fig. 1. (Color online) Schematic illustration of the whole fabrication procedure of Cu2O NWs by AAO template: gold layer deposition (I), Ni electrodeposition (II), aluminum and barrier layer removal (III), Cu2O growth (IV), and template removal (V).
Fig. 2. (Color online) SEM images of (a) the as-prepared AAO template, (b) Cu2O NWs (inset is cross-sectional SEM image of Cu2O NWs) and (c) Cu2O films. (d) The corresponding XRD patterns of Cu2O NWs and films (inset is mapping of Cu2O NWs).
Fig. 3. (Color online) (a) EQY spectra, (b) photocurrent–potential profiles, (c) time-dependent photocurrent density spectra and (d) impedance spectra of the Cu2O NWs and films photoelectrode.
Fig. 4. (Color online) (a) Top-view SEM image of Cu2O NWs with Pt NPs. (b) Photocurrent–potential curves and (c) photocurrent-time profile at –0.3 V versus Ag/Ag and (d) EQY spectra of the photoelectrode based on Cu2O NWs with Pt NPs. The inset is impendence spectra.
Fig. 5. (Color online) (a) Schematic diagram of Cu2O NWs/Pt photoelectrode and (b) energy band-gap spectrum of the Cu2O NWs with/without Pt NPs.
