integration of a cocatalyst and heterojunction to a WO photoanode with enhanced photoelectrochemical performance phosphatization
A novel ternary NiP x /NiWO 4 /WO 3 photoanode with the cooperation effect of a heterojunction and cocatalyst was successfully fabricated by an in situ phosphatization process. The NiWO 4 layer forms a heterojunction with WO 3 to improve the separation and transfer of electron-hole pairs. NiP x acts...

Zusammenfassung: | A novel ternary NiP
x
/NiWO
4
/WO
3
photoanode with the cooperation effect of a heterojunction and cocatalyst was successfully fabricated by an
in situ
phosphatization process. The NiWO
4
layer forms a heterojunction with WO
3
to improve the separation and transfer of electron-hole pairs. NiP
x
acts as a cocatalyst for accelerating the surface water oxidation reaction. A 2.55-fold improvement in photocurrent density at 1.23 V
vs.
RHE was achieved compared with the pristine WO
3
film.
